(1,3)-Beta-D-Glucan (Aspergillus) Test in UAE
(1,3)-Beta-D-Glucan test in Dubai and across the UAE to detect early signs of fungal infections like Aspergillus. This sensitive blood test helps identify invasive fungal infections in high-risk patients — including those with weakened immunity, post-transplant, or on chemotherapy. Results available within 15 days.
Overview
The (1,3)-Beta-D-Glucan test is a serum-based biomarker assay that detects a key component of fungal cell walls. It is highly useful in the early identification of invasive fungal infections, including Aspergillus, Candida, and Pneumocystis jirovecii. This test does not identify the specific fungus but signals the presence of a fungal infection, enabling earlier treatment. Results are typically available within 15 days.
Why You Need This Test
- Early detection of invasive fungal infections in immunocompromised individuals (e.g., cancer, transplant, or ICU patients).
- Monitor patients on long-term steroids or immunosuppressive therapy.
- Support diagnosis when symptoms include fever, cough, chest pain, or shortness of breath unresponsive to antibiotics.
- Complement imaging (e.g., CT scan) and other tests like galactomannan or fungal culture.
- Reduce delays in starting antifungal therapy — critical for survival in high-risk groups.
- Non-invasive alternative to lung biopsy for suspected Aspergillus.
- Available with home sample collection across Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms
- Persistent fever not responding to antibiotics.
- Dry cough or chest pain — may mimic pneumonia.
- Shortness of breath or hypoxia.
- Fatigue and night sweats.
- Hemoptysis (coughing up blood) in advanced cases.
Risk Factors
- Weakened immune system: HIV/AIDS, chemotherapy, organ/bone marrow transplant.
- Long-term corticosteroid use or immunosuppressants.
- Lung diseases: COPD, cystic fibrosis, prior TB.
- ICU admission with mechanical ventilation.
- Neutropenia (low white blood cells).
- Exposure to construction/dust (source of Aspergillus spores).
How the Test Works
The test detects (1,3)-beta-D-glucan, a polysaccharide found in the cell walls of many pathogenic fungi (except Cryptococcus and mucormycetes). A positive result suggests fungal invasion, even before cultures turn positive.
- Step 1 — Appointment: visit a certified lab or book home blood collection (available in Dubai, Abu Dhabi, Sharjah, and other Emirates).
- Step 2 — Blood draw: a trained technician collects a serum sample (plain tube) via venipuncture (takes under 5 minutes).
- Step 3 — Lab analysis: performed using sensitive immunoassay to detect glucan levels.
- Step 4 — Results: delivered securely within 15 business days.
This test supports early clinical decisions — especially when imaging or cultures are inconclusive.

ABPA MINI panel(Allergic bronchopulmonary aspergillosis) Test in UAE
ABPA MINI Panel (Allergic Bronchopulmonary Aspergillosis) Test in Dubai and across the UAE to detect fungal hypersensitivity in asthma and cystic fibrosis patients. This specialized blood test helps diagnose ABPA — a serious allergic reaction to the Aspergillus fumigatus mold that can cause progressive lung damage if untreated. Combines key biomarkers for accurate detection. Results available within 5–7 days.
Overview
The ABPA MINI Panel is a targeted blood test used to diagnose Allergic Bronchopulmonary Aspergillosis (ABPA), a condition where the immune system overreacts to Aspergillus fumigatus, a common fungus found in dust and decaying organic matter. It primarily affects individuals with asthma or cystic fibrosis, leading to worsening respiratory symptoms and potential lung damage. The panel measures total IgE, Aspergillus-specific IgE, and Aspergillus precipitins (IgG) — key markers for confirming ABPA. Results are typically available within 5–7 business days.
Why You Need This Test
- Diagnose ABPA in patients with uncontrolled asthma or cystic fibrosis.
- Evaluate worsening cough, wheezing, or recurrent chest infections.
- Detect fungal sensitization before permanent lung damage occurs.
- Monitor disease progression or response to steroid/antifungal therapy.
- Rule out fungal bronchitis or aspergilloma in lung imaging abnormalities.
- Support early intervention to prevent bronchiectasis or pulmonary fibrosis.
- Available with home blood collection service across Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms
- Worsening asthma not responding to standard inhalers
- Chronic cough with brownish mucus plugs
- Wheezing and shortness of breath
- Fever or malaise without active infection
- Chest tightness or recurrent pneumonia-like episodes
Risk Factors
- Long-standing asthma, especially moderate to severe
- Cystic fibrosis (CF) — up to 15% develop ABPA
- High exposure to mold (e.g., farming, composting, damp environments)
- Elevated IgE levels on prior testing
- History of pulmonary infiltrates on chest X-ray or CT scan

ABPA SCREEN (TOTAL IGE SPECIFIC IGE AF) Test in UAE
ABPA Screen (Total IgE & Specific IgE Af) test available in Dubai and across the UAE to detect allergic bronchopulmonary aspergillosis (ABPA), a hypersensitivity reaction to the fungus Aspergillus fumigatus. This comprehensive screening measures both total IgE levels and specific IgE antibodies against Aspergillus fumigatus, aiding early diagnosis in patients with asthma or cystic fibrosis. Results available within 5–7 days.
Overview
The ABPA Screen is a blood test that evaluates the immune response to Aspergillus fumigatus, a common mold found in the environment. It includes measurement of total immunoglobulin E (IgE) and specific IgE antibodies directed against Aspergillus fumigatus (Af). Elevated levels suggest an allergic reaction in the lungs, commonly seen in allergic bronchopulmonary aspergillosis (ABPA), a condition that can mimic or worsen asthma and cystic fibrosis. This test is crucial for early detection and preventing lung damage. Results are typically available within 5–7 business days.
Why You Need This Test
- Diagnose allergic bronchopulmonary aspergillosis (ABPA) in patients with poorly controlled asthma or cystic fibrosis.
- Evaluate chronic cough, wheezing, or recurrent chest infections unresponsive to standard treatment.
- Investigate elevated total IgE levels without clear allergic cause.
- Monitor disease progression or treatment response in known ABPA cases.
- Assess patients with central bronchiectasis on imaging.
- Support diagnosis when sputum culture shows Aspergillus but infection is not confirmed.
- Available with home blood collection in Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms
- Wheezing or worsening asthma not responding to inhalers
- Chronic cough with brownish mucus plugs
- Fever or malaise without infection
- Shortness of breath during routine activities
- Chest tightness or recurrent pneumonia-like episodes
Risk Factors

ACID FAST BACILLI (AFB) CULTURE ( BLOOD & / BONE MARROW) Test in UAE
Acetylcholinesterase (OPC Poisoning) Plasma Test in Dubai and across the UAE to detect and monitor organophosphate or carbamate pesticide exposure. This critical test measures enzyme activity in the blood, helping confirm organophosphate compound (OPC) poisoning — a life-threatening condition often caused by insecticide exposure. Results available within 7–10 days.
Overview
The Acetylcholinesterase Plasma Test measures the activity of acetylcholinesterase — an enzyme essential for normal nerve function — in the bloodstream. Organophosphate (OP) and carbamate pesticides inhibit this enzyme, leading to toxic accumulation of acetylcholine and severe neurological symptoms. This test is vital for confirming exposure, assessing severity, and guiding treatment in suspected poisoning cases. It is especially important for agricultural workers, emergency cases, and patients with unexplained neurological symptoms. Results are typically available within 7–10 business days.
Why You Need This Test
- Confirm organophosphate or carbamate pesticide poisoning in acute or chronic exposure.
- Evaluate patients with unexplained neurological symptoms after chemical exposure.
- Assess severity of poisoning and guide antidote therapy (e.g., atropine, pralidoxime).
- Monitor recovery and enzyme regeneration during treatment.
- Screen agricultural, pest control, or industrial workers with potential exposure.
- Support diagnosis in cases of intentional ingestion or suicide attempts.
- Available with rapid blood draw services across Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms (Acute Poisoning)
- Muscle twitching, weakness, or paralysis
- Excessive salivation, sweating, or tearing
- Nausea, vomiting, or diarrhea
- Breathing difficulties or bronchospasm
- Blurred vision or pinpoint pupils (miosis)
- Anxiety, confusion, or seizures
- Low heart rate (bradycardia)
Risk Factors
- Occupational exposure to pesticides (farmers, sprayers, gardeners)
- Living in agricultural areas with frequent pesticide use
- Poor use of protective equipment during chemical handling
- Ingestion of contaminated food or water
- Intentional self-harm using insecticides
- Chronic low-level exposure leading to subtle neurological effects
How the Test Works
Organophosphates and carbamates block acetylcholinesterase, the enzyme that breaks down acetylcholine in nerve endings. When inhibited, acetylcholine builds up, causing continuous nerve signaling and toxic effects. The plasma acetylcholinesterase test measures enzyme activity in blood — lower levels indicate greater exposure and poisoning severity.
- Step 1 — Blood draw: a healthcare professional collects a blood sample from your arm.
- Step 2 — Sample handling: plasma is separated and preserved for specialized testing.
- Step 3 — Laboratory analysis: enzyme activity is measured using spectrophotometric methods.
- Step 4 — Interpretation: results compared to normal reference ranges.
- Step 5 — Results: securely delivered within 7–10 business days.
This test is crucial for diagnosing and managing a potentially fatal condition.
Sample Type
- We take: Blood sample (plasma)
- Volume: 3–5 mL collected in a green-top (heparin) or specific enzyme tube
- Collection: venous blood draw from the arm
- Handling: must be processed within 4–6 hours; plasma separated and frozen
- Storage: stored at -20°C or lower until analysis
- Note: delayed processing or hemolyzed samples may affect accuracy
Risks & Safety
- Minimal risk — standard blood draw with slight pain or bruising at the site.
- No fasting or special prep required unless directed.
- Safe for adults and children when medically necessary.
- Critical in emergencies — helps guide life-saving treatment.
Result Interpretation
Normal Range
- Normal: Varies by lab — typically 5,000–12,000 U/L (method-dependent)
- Baseline levels differ between individuals; serial testing is more informative
Reduced Activity
- 50–70% of normal: Mild inhibition — possible early or chronic exposure
- 30–50% of normal: Moderate poisoning — clinical symptoms likely
- Below 30%: Severe inhibition — high risk of respiratory failure
- Strongly suggests:
- Organophosphate poisoning
- Carbamate exposure
- Chronic pesticide contact
Important Notes
- Plasma cholinesterase (pseudo-cholinesterase) declines faster than red blood cell enzyme.
- Levels may regenerate in days to weeks after exposure ends.
- Results should be correlated with clinical symptoms and exposure history.
Consequences if Untreated
- Respiratory failure due to paralysis of breathing muscles.
- Seizures or coma from uncontrolled nerve activity.
- Prolonged ICU stay and mechanical ventilation.
- Intermediate syndrome (muscle weakness 24–96 hrs post-exposure).
- Long-term neurological damage or cognitive deficits.
- Death if not diagnosed and treated promptly.
Factors Affecting Test Results
- Time since exposure: enzyme levels drop rapidly after poisoning.
- Treatment with oximes: may partially restore enzyme activity.
- Genetic variations: some people naturally have lower baseline levels.
- Liver disease: reduces enzyme production.
- Pregnancy: may lower plasma cholinesterase.
- Sample delay: improper handling can degrade enzyme activity.
- Other toxins: certain drugs or chemicals may interfere.

ACID FAST BACILLI (AFB) CULTURE (Extra Pulmonary): MGIT Test in UAE
Acid Fast Bacilli (AFB) Culture (Blood & Bone Marrow) test in Dubai and across the UAE to detect mycobacterial infections, including tuberculosis (TB) and disseminated (systemic) mycobacteriosis. This specialized culture test is essential when TB is suspected beyond the lungs — such as in bone marrow, bloodstream, or immune-compromised patients. Results available within 4–6 weeks.
Overview
The Acid Fast Bacilli (AFB) Culture from blood or bone marrow is a definitive diagnostic test to identify the presence of slow-growing mycobacteria, primarily Mycobacterium tuberculosis and non-tuberculous mycobacteria (NTM). Unlike rapid tests, culture remains the gold standard for confirming active infection, enabling species identification and antibiotic susceptibility testing. Due to the slow growth of these organisms, results typically take 4–6 weeks. This test is crucial for diagnosing extrapulmonary and disseminated TB, especially in immunocompromised individuals.
Why You Need This Test
- Diagnose disseminated tuberculosis (miliary TB) — when TB spreads through the bloodstream.
- Evaluate unexplained fever of unknown origin (FUO) lasting weeks.
- Confirm infection in patients with HIV/AIDS, organ transplant, or on immunosuppressive therapy.
- Investigate anemia, low platelets, or abnormal bone marrow findings.
- Detect mycobacteremia (bacteria in the blood) in critically ill patients.
- Guide targeted antibiotic treatment based on culture and sensitivity results.
- Available at specialized labs in Dubai, Abu Dhabi, Sharjah, and across the UAE with expert microbiology support.
Symptoms & Risk Factors
Common Symptoms
- Prolonged fever (lasting >2–3 weeks) without clear cause
- Night sweats, chills, and fatigue
- Unintentional weight loss and loss of appetite
- Pallor, weakness, or bleeding (due to bone marrow involvement)
- Enlarged lymph nodes, liver, or spleen
- Joint pain or back pain (if spine is involved)
Risk Factors
- HIV infection or advanced immune suppression
- History of pulmonary or extrapulmonary TB
- Close contact with someone who has active TB
- Living in or traveling to high-TB-burden countries
- Organ transplant recipients or those on chemotherapy/biologics
- Chronic kidney disease or diabetes
- Recent bone marrow biopsy with suspicious findings
How the Test Works
AFB culture detects live mycobacteria in blood or bone marrow samples. These bacteria grow extremely slowly and require special nutrient media and prolonged incubation.
- Step 1 — Sample collection: blood drawn via venipuncture or bone marrow aspirate collected by a hematologist or specialist.
- Step 2 — Inoculation: sample is placed into liquid and solid culture media that support mycobacterial growth.
- Step 3 — Incubation: cultures are monitored for up to 6 weeks using automated systems (e.g., MGIT).
- Step 4 — Identification: any growth is confirmed as M. tuberculosis or NTM using molecular tests (e.g., PCR).
- Step 5 — Sensitivity testing: determines which antibiotics will effectively treat the infection.
- Step 6 — Results: final report delivered within 4–6 weeks.
This test is vital for confirming systemic TB and ensuring accurate, life-saving treatment.
Sample Type
- We take:
- Blood: 5–10 mL collected in AFB culture bottles (sterile conditions)
- Bone Marrow: aspirate collected under local anesthesia by a specialist
- Volume: depends on patient age and clinical indication
- Collection method: sterile technique to prevent contamination
- Transport: immediate delivery to the lab under controlled conditions
- Note: bone marrow procedure is performed at hospitals or clinics; blood draw available at collection centers
Risks & Safety
- Blood draw: minimal risk — slight pain, bruising, or infection at the site.
- Bone marrow aspiration: performed under local anesthesia; may cause brief pain, pressure, or soreness.
- No risk of spreading TB to others during sample collection when proper precautions are followed.
- Safe for adults and older children under medical supervision.
Result Interpretation
Normal Range
- Negative: No growth of acid-fast bacilli after 6 weeks
- Indicates absence of systemic mycobacterial infection (but does not rule out localized TB)
Positive Result
- Indicates:
- Mycobacterium tuberculosis complex — confirms active TB infection
- Non-tuberculous mycobacteria (NTM) — may be pathogenic or contaminant
- Further testing (e.g., PCR, sensitivity) will identify the exact species and guide treatment.
Contamination or Indeterminate
- Rarely, skin flora may contaminate the sample — lab will report accordingly.
- If clinical suspicion remains high, repeat testing or alternative diagnostics may be needed.
Consequences if Untreated
- Progressive, life-threatening infection affecting multiple organs.
- Severe anemia, bleeding, or bone marrow failure due to marrow involvement.
- Spread to brain (TB meningitis), spine, or liver.
- Multi-organ failure in immunocompromised patients.
- Drug-resistant TB if incorrect or delayed treatment is started.
Factors Affecting Test Results
- Antibiotic use: prior TB drugs may suppress growth and cause false-negative results.
- Small sample volume: reduces detection sensitivity.
- Improper handling or delay in transport: can kill bacteria before culture.
- Low bacterial load: common in early or mild disease.
- Immune status: HIV+ patients may have higher yield in blood cultures.
- Lab expertise: requires specialized biosafety level 3 (BSL-3) facilities.

Acid Fast Bacilli (AFB) Culture (Extra Pulmonary): MGIT Test in Dubai and across the UAE to detect tuberculosis (TB) outside the lungs. This advanced diagnostic test identifies *Mycobacterium tuberculosis* in non-respiratory samples such as lymph nodes, urine, cerebrospinal fluid (CSF), joint fluid, or tissue biopsies. Using the automated MGIT (Mycobacteria Growth Indicator Tube) system, it offers high sensitivity and faster detection than traditional methods. Results available within 4–6 weeks.
Overview
The AFB Culture (Extra Pulmonary): MGIT Test is a highly sensitive microbiological test used to confirm the presence of *Mycobacterium tuberculosis* in body fluids or tissues other than sputum. Unlike smear microscopy, which only detects visible bacilli, culture allows for definitive identification and viability testing. The **MGIT system** uses fluorescent technology to detect growth early, improving diagnostic accuracy. This test is essential for diagnosing **extrapulmonary TB**, a challenging form of infection that can affect the lymph nodes, brain, kidneys, bones, and abdomen. Results are typically available within 4–6 weeks due to the slow-growing nature of mycobacteria.
Why You Need This Test
- Confirm diagnosis of extrapulmonary tuberculosis (TB) when symptoms suggest infection outside the lungs.
- Evaluate patients with enlarged lymph nodes, meningitis, or unexplained fever.
- Test body fluids such as CSF, pleural fluid, ascites, synovial fluid, or urine.
- Analyze tissue biopsies from lymph nodes, bone, or abdominal organs.
- Follow-up after positive AFB smear or GeneXpert result from non-respiratory samples.
- Differentiate between TB and other chronic infections or cancers.
- Available at accredited laboratories across Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms
- Persistent fever or night sweats without clear cause
- Unexplained weight loss and fatigue
- Swollen lymph nodes (especially in neck or groin)
- Headaches, confusion, or seizures (if TB affects the brain — tuberculous meningitis)
- Painful or swollen joints (TB arthritis)
- Abdominal pain, swelling, or ascites (peritoneal TB)
- Blood in urine or frequent urination (renal TB)
Risk Factors
- Known exposure to active TB (household or close contact)
- History of latent or pulmonary TB
- Low immunity due to HIV/AIDS, diabetes, or steroid use
- Organ transplant recipients on immunosuppressive drugs
- Healthcare workers exposed to TB patients
- Living in or traveling to high-TB-burden countries
- Malnutrition or chronic illness
How the Test Works
The MGIT (Mycobacteria Growth Indicator Tube) system is an automated liquid culture method that detects the growth of acid-fast bacilli, including *M. tuberculosis*, in non-pulmonary specimens. It is more sensitive than solid culture and provides results faster.
- Step 1 — Sample collection: a clinical sample (e.g., lymph node aspirate, CSF, urine, tissue) is collected by a healthcare provider using sterile technique.
- Step 2 — Transport: the sample is placed in a sterile container and sent to a certified lab under controlled conditions.
- Step 3 — Inoculation: the sample is processed and inoculated into MGIT tubes containing growth medium and a fluorescent sensor.
- Step 4 — Incubation: tubes are incubated in an automated system that monitors for fluorescence indicating bacterial growth.
- Step 5 — Identification: positive cultures are further tested with molecular methods (e.g., PCR) to confirm *M. tuberculosis*.
- Step 6 — Results: final report available within 4–6 weeks.
This test is critical for diagnosing hidden forms of TB that are easily missed without proper culture.
Sample Type
- We test: Non-respiratory clinical specimens such as:
- Cerebrospinal fluid (CSF)
- Lymph node aspirate or biopsy
- Urine
- Pleural, peritoneal, or synovial fluid
- Tissue samples (e.g., liver, bone marrow)
- Volume: varies by sample type (e.g., 5–10 mL CSF, 20–50 mL urine, full aspirate volume)

How the Test Works
The MGIT (Mycobacteria Growth Indicator Tube) system is an automated liquid culture method that enhances the growth and detection of Mycobacterium tuberculosis from sputum samples.
- Step 1 — Sample collection: collect 2–3 early morning sputum samples (ideally on consecutive days).
- Step 2 — Processing: sputum is treated to liquefy and concentrate the bacteria.
- Step 3 — Inoculation: sample is placed into MGIT tubes containing growth medium and a fluorescent sensor.
- Step 4 — Incubation: tubes are incubated in an automated system that monitors for bacterial growth.
- Step 5 — Detection: if mycobacteria grow, they consume oxygen, triggering fluorescence — detected by the machine.
- Step 6 — Identification & DST: positive cultures are further tested to confirm M. tuberculosis and check for drug resistance.
- Step 7 — Results: final report delivered securely within 4–6 weeks.
This test is critical for accurate diagnosis and effective treatment planning.
Sample Type
- We take: Expectorated sputum (from deep lungs, not saliva)
- Number of samples: 2–3 early morning specimens (on separate days preferred)
- Volume: at least 3–5 mL per sample
- Collection method: deep cough into sterile container after rinsing mouth
- Transport: samples must be sealed and delivered to the lab promptly (or stored at 4°C if delayed)
- Note: saliva-only or dry cough samples may be rejected due to low diagnostic value
Risks & Safety

Acid Fast Stain (ZN Stain) for Mycobacterium, AFB smear Test in UAE
Acid Fast Stain (ZN Stain) for Mycobacterium, AFB Smear Test in Dubai and across the UAE to rapidly detect acid-fast bacilli (AFB), including Mycobacterium tuberculosis — the cause of TB. This essential screening test uses the **Ziehl-Neelsen (ZN) staining technique** to identify bacteria in sputum and other clinical samples. Results available within 1–2 days.
Overview
The Acid Fast Stain (ZN Stain) – AFB Smear Test is a rapid microscopic test used to detect the presence of acid-fast bacilli, primarily Mycobacterium tuberculosis, in clinical specimens such as sputum, bronchoalveolar lavage (BAL), urine, or tissue. The Ziehl-Neelsen (ZN) staining method uses carbol fuchsin and counterstains to highlight mycobacteria under the microscope. These bacteria retain the red dye even after acid-alcohol treatment — hence "acid-fast." This test is a **first-line tool in diagnosing tuberculosis (TB)** and other mycobacterial infections. Results are typically available within 1–2 business days.
Why You Need This Test
- Screen for pulmonary tuberculosis (TB) in patients with persistent cough, fever, or weight loss.
- Diagnose extrapulmonary TB using urine, CSF, lymph node aspirates, or tissue samples.
- Support early detection of active TB infection before culture results are ready.
- Monitor treatment response in known TB patients (declining AFB counts).
- Essential for infection control in hospitals and clinics.
- Fast, cost-effective, and widely used in high-prevalence regions.
- Available with home sputum collection support across Dubai, Abu Dhabi, Sharjah, and all Emirates.
Symptoms & Risk Factors
Common Symptoms
- Chronic cough lasting more than 2–3 weeks
- Coughing up blood (hemoptysis)
- Fever, night sweats, and chills
- Unexplained weight loss and fatigue
- Chest pain or difficulty breathing
Risk Factors
- Close contact with a person diagnosed with active TB
- Living or working in crowded environments (e.g., labor camps, prisons)
- Healthcare workers exposed to TB patients
- Smoking or lung disease (COPD, silicosis)
- Weakened immune system (HIV, diabetes, steroid use)
- Recent travel to or origin from high-TB-burden countries
How the Test Works
The Ziehl-Neelsen (ZN) stain is a histological technique that identifies mycobacteria based on their unique waxy cell wall, which resists decolorization by acid alcohol after staining.
- Step 1 — Sample collection: sputum is collected (preferably early morning, deep cough), or other specimen types (urine, CSF, tissue) are submitted.
- Step 2 — Smear preparation: a thin layer of the sample is spread on a glass slide and heat-fixed.
- Step 3 — Staining: slides are treated with carbol fuchsin (red dye), then decolorized with acid-alcohol, and counterstained with methylene blue.
- Step 4 — Microscopy: examined under oil immersion for red, rod-shaped bacteria (acid-fast bacilli).
- Step 5 — Results: reported as negative or positive with semi-quantitative grading (e.g., 1+ to 4+).
This test provides a rapid clue to TB infection — critical for early isolation and treatment.
Sample Type
- We accept: Sputum (most common), BAL, gastric aspirate, urine, CSF, pleural fluid, tissue biopsies
- Preferred sample: Early morning sputum (3 consecutive days may be requested)
- Volume: 3–5 mL of sputum; minimum 1 mL for other fluids
- Container: Sterile, leak-proof, wide-mouthed sputum cup
- Labeling: Must include patient name, date, and time of collection
- Note: Saliva or oropharyngeal secretions are inadequate — deep cough sputum required
Risks & Safety
- No physical risk from the test itself (non-invasive sample collection).
- Sputum induction (if needed) may cause mild coughing or discomfort.
- Specimen handling follows strict biosafety protocols (BSL-3 for TB suspects).
- Safe for adults and children over 5 years old (younger children may require gastric aspirate).
Result Interpretation
Normal Range
- Negative: No acid-fast bacilli seen (0 AFB per 100 oil immersion fields)
- A negative result does not rule out TB — culture and PCR may still be needed
Positive Results
- Reported as:
- Scanty: 1–9 AFB in 100 fields
- 1+: 10–99 AFB in 100 fields
- 2+: 1–10 AFB per field (in 50 fields)
- 3+: >10 AFB per field (in 20 fields)
- 4+: Too numerous to count
- A positive result suggests:
- Pulmonary tuberculosis
- Other mycobacterial infections (e.g., M. avium)
- Requires confirmation with AFB culture and molecular testing (e.g., Xpert MTB/RIF)
Consequences if Untreated
- Progression to severe lung damage and chronic respiratory failure.
- Spread of infection to others via airborne droplets.
- Disseminated (miliary) TB affecting brain, spine, kidneys, or bones.
- TB meningitis — life-threatening if not treated early.
- Drug-resistant TB development with delayed diagnosis.
- Increased mortality, especially in immunocompromised individuals.
Factors Affecting Test Results

Hepatitis B "s" Ag (HBs Ag)
Hepatitis B “s” Ag (HBs Ag) Test – Screen for Hepatitis B Infection
The Hepatitis B Surface Antigen (HBs Ag) Test detects the presence of the hepatitis B surface antigen in the blood, indicating an active hepatitis B virus (HBV) infection. This test is a cornerstone of viral hepatitis screening and is used to diagnose acute or chronic HBV, monitor infection status, and determine immunity or carrier state.
Symptoms That Indicate You May Need This Test
If you experience any of the following, especially with risk factors like IV drug use, unprotected sex, or travel to endemic areas:
- Fatigue and weakness
- Jaundice (yellowing of skin and eyes)
- Dark urine and pale stools
- Abdominal pain, especially in the upper right quadrant
- Nausea, vomiting, or loss of appetite
- Joint pain and fever
These may indicate acute hepatitis B infection. However, many people are asymptomatic, making screening essential.
Natural Production and Role in the Body
The hepatitis B surface antigen (HBsAg) is a protein found on the surface of the hepatitis B virus. It appears in the blood 6–16 weeks after exposure and is the first marker of infection. Its presence indicates that the virus is actively replicating and the person is contagious. In acute infection, HBsAg usually disappears within 6 months. Persistence beyond 6 months suggests chronic infection.
What Happens If Left Untreated?
Chronic hepatitis B can lead to severe liver complications, including:
- Cirrhosis (scarring of the liver)
- Liver failure
- Hepatocellular carcinoma (liver cancer)
- Transmission to others through blood or bodily fluids
- Fulminant hepatitis (rare but life-threatening)
Early detection allows for monitoring, antiviral treatment, and lifestyle changes to protect liver health.
Test Overview
A 2 mL blood sample is collected in an SST or red-top tube. The test uses immunoassay methods to detect HBsAg in serum. Results are typically available the same day. A positive result requires follow-up testing (e.g., HBV DNA, liver function tests) to determine infection stage and treatment needs.
Frequently Asked Questions (FAQs)
Can I have hepatitis B without symptoms?
Yes—many people, especially children, have no symptoms but can still spread the virus.
Does a positive test mean I’m immune?
No—positive HBsAg means active infection. Immunity is indicated by positive anti-HBs antibodies, usually from vaccination or recovery.
Who should get tested?
Recommended for pregnant women, healthcare workers, people with multiple sexual partners, IV drug users, and those from regions with high HBV prevalence.

Herpes Simplex Virus (HSV)-I, IgM
Herpes Simplex Virus (HSV)-I, IgM Test in UAE
Overview
The HSV-1 IgM blood test helps detect recent or active infection caused by Herpes Simplex Virus type 1 (HSV-1). HSV-1 is most commonly associated with oral herpes (cold sores) and can also cause genital herpes, eye infections, and complications in pregnancy. Testing requires a simple blood sample, and results are typically ready within 2 days.
Symptoms & Risk Factors
Common Symptoms
- Painful blisters or cold sores on lips, mouth, or face
- Burning, itching, or tingling sensation before sores appear
- Swollen lymph nodes and mild fever
- Sore throat or flu-like illness
- Genital ulcers or painful urination (if sexually transmitted)
Risk Factors
- Unprotected oral or sexual contact with an infected person
- Weakened immune system (HIV, cancer therapy, chronic illness)
- Pregnancy — increased risk of neonatal herpes transmission
- Sharing utensils, razors, or close contact during outbreaks
How the Test Works
- Sample collection: A small blood sample (serum) is drawn from the arm.
- Laboratory analysis: The sample is tested for HSV-1 IgM antibodies, which appear in early or reactivated infection.
- Results: A secure report is provided within 2 working days.
Specimen (Sample Type)
- Sample required: Serum, plain
- Volume: 1 mL
- Collection method: Standard venipuncture
Risks & Safety
- Mild pain, swelling, or bruising at the blood draw site
- Occasional dizziness or fainting
- Minimal infection risk with sterile technique
About Herpes Simplex Virus (HSV-1)
HSV-1 is a lifelong viral infection that becomes dormant in nerve cells and may reactivate under certain conditions. While it most often causes cold sores, it can also lead to genital herpes, eye infections, or rarely encephalitis. Detecting HSV-1 IgM antibodies helps confirm recent or active infection for timely care.
Result Interpretation
- Positive IgM: Indicates recent or current HSV-1 infection.
- Negative IgM: Suggests no recent infection; past exposure may still be present (check HSV-1 IgG).
- Your clinician may recommend HSV IgG, PCR, or culture for confirmation.
Consequences if Untreated
- Recurrent painful outbreaks that affect daily comfort
- Higher risk of transmission to partners or newborns
- Rare but serious complications (e.g., herpes encephalitis, eye damage)
- Emotional distress and social stigma during visible outbreaks
Factors Affecting Symptoms
- Stress, illness, or weakened immunity can trigger recurrences
- Sunlight exposure or fever may reactivate the virus
- Overall health and nutrition influence recurrence frequency
Related Tests
- HSV-1 IgG Test (to detect past infection)
- HSV-2 IgM/IgG Tests
- PCR for HSV (detects viral DNA directly)

HIV Combi (Type 1 & 2 Antibodies + p24 Antigen)
HIV Combi Test – Early Detection of HIV-1 and HIV-2 Infection
The HIV Combi Test detects both HIV-1 and HIV-2 antibodies and the p24 antigen in blood, making it one of the most accurate and early diagnostic tools for HIV infection. This fourth-generation test can identify HIV as early as 2–3 weeks after exposure, significantly reducing the window period and enabling prompt medical intervention.
Symptoms That Indicate You May Need This Test
If you've had potential exposure to HIV (e.g., unprotected sex, shared needles) and experience any of the following flu-like symptoms, testing is crucial:
- Fever, chills, or night sweats
- Fatigue and body aches
- Sore throat and swollen lymph nodes
- Rash on the trunk or limbs
- Mouth ulcers or genital sores
These may indicate acute HIV infection (seroconversion illness), which often goes unrecognized.
Natural Production and Role in the Body
After HIV enters the body, the virus begins replicating rapidly. The p24 antigen is a viral protein that appears in the blood 10–15 days post-exposure, before antibodies develop. Antibodies to HIV-1 and HIV-2 typically appear 3–8 weeks later. The combi test detects both markers, allowing earlier diagnosis than antibody-only tests.
What Happens If Left Untreated?
Untreated HIV progressively destroys CD4 immune cells, leading to:
- Severe immunodeficiency (AIDS)
- Opportunistic infections (e.g., TB, pneumocystis pneumonia)
- Certain cancers (e.g., Kaposi’s sarcoma)
- Neurological complications
- Transmission to others through blood, sexual contact, or mother-to-child
Early detection allows immediate antiretroviral therapy (ART), which suppresses the virus and prevents progression.
Test Overview
A 2 mL blood sample is collected in an SST or red-top tube. The test uses chemiluminescent immunoassay (CLIA) technology to detect p24 antigen and HIV-1/2 antibodies simultaneously. Results are typically available the same day. A positive result requires confirmation with a Western Blot or HIV-1 RNA PCR test.
Frequently Asked Questions (FAQs)
How soon can this test detect HIV?
As early as 2–3 weeks after exposure, thanks to p27 antigen detection.
Is this test more accurate than older HIV tests?
Yes—fourth-generation combi tests reduce the diagnostic window by 5–7 days compared to antibody-only tests.
Can I test negative and still be infected?
Possible during the window period. Retesting after 4 weeks is recommended if exposure was recent.

Salmonella Antibody Test (Salmonella Abs)
Salmonella Antibodies Test – Detect Typhoid and Systemic Infections
The Salmonella Antibodies Test detects IgG and IgM antibodies against Salmonella typhi and other Salmonella species in the blood. This serological test is used to diagnose typhoid fever and systemic salmonellosis, particularly when stool cultures are negative or delayed. It is especially valuable for travelers returning from endemic regions.
Symptoms That Indicate You May Need This Test
If you have the following symptoms, especially after consuming contaminated food or traveling abroad:
- High, sustained fever (103–104°F)
- Abdominal pain and bloating
- Diarrhea or constipation
- Headache, weakness, and fatigue
- Loss of appetite
- Rose spots (pink, flat spots on the chest or abdomen)
These are classic signs of typhoid fever caused by S. typhi.
Natural Production and Role in the Body
When Salmonella bacteria enter the body through contaminated food or water, the immune system responds by producing specific antibodies. IgM appears within 1 week of infection, indicating acute or recent exposure. IgG rises later and may persist for months or years, suggesting past infection or vaccination.
What Happens If Left Untreated?
Untreated typhoid fever can lead to severe complications, including:
- Intestinal perforation and peritonitis
- Life-threatening sepsis
- Encephalopathy or meningitis
- Chronic carrier state (asymptomatic shedding in stool)
- Death in up to 10–20% of untreated cases
Early diagnosis and antibiotic treatment are critical to recovery.
Test Overview
A 2 mL blood sample is drawn from a vein and collected in an SST or red-top tube. The test detects antibody titers in serum. A rising titer between acute and convalescent samples (taken 1–2 weeks apart) confirms active infection. Results are typically available the same day.
Frequently Asked Questions (FAQs)
Can this test give false positives?
Yes—previous infection, vaccination, or cross-reacting infections (like malaria) may cause elevated IgG. IgM is more specific for recent infection.
Is this test better than stool culture?
It's complementary. Blood antibodies are useful when cultures are negative or delayed.
Do I need a repeat test?
Sometimes—doctors may order a second test 1–2 weeks later to confirm rising antibody levels.
