Hepatitis B “s” Ag (HBsAg) Test – Accurate & Easy Detection

The Hepatitis B Surface Antigen (HBsAg) Test from Lab Tests Dubai is a critical blood test that detects the presence of Hepatitis B surface antigen (HBsAg)—a protein found on the surface of the Hepatitis B virus (HBV)—in your bloodstream.

This test is the primary screening tool for active Hepatitis B infection, whether acute (recent) or chronic (lasting more than 6 months). A positive result means the virus is present and you can transmit it to others through blood, semen, or other body fluids.

This test is essential for:

• Pregnant women (to prevent mother-to-child transmission)
• Healthcare workers and first responders
• Individuals with high-risk behaviors (unprotected sex, IV drug use)
• People with symptoms of liver disease (jaundice, fatigue, dark urine)
• Pre-employment, visa, or pre-surgery screening
• Family members of infected individuals

Using high-sensitivity chemiluminescence technology, this serum-based test delivers accurate results within just 1 day, helping doctors diagnose early, prevent spread, and start treatment.

Available with home blood collection, Lab Tests Dubai ensures fast, accurate, and stress-free testing—so you can protect your liver and your loved ones.

Why You Need This Test

If you’ve had unprotected sex, a needle stick injury, or feel unusually tired and yellow-eyed, this test could reveal a silent liver infection that’s easily treatable if caught early.

You need the HBsAg Test if:

• You’re pregnant or planning pregnancy
• You’ve had unprotected sex or shared needles
• You’re a healthcare worker or lab technician
• You have family or household contact with HBV
• You’ve traveled to or lived in high-prevalence regions (Africa, Asia, Middle East)
• You’re undergoing surgery, dialysis, or organ transplant
• You have symptoms of liver disease

This test helps:

• Confirm active Hepatitis B infection
• Prevent transmission to partners, babies, or coworkers
• Start antiviral therapy early (if chronic)
• Avoid liver damage, cirrhosis, or cancer

Early detection = liver protection and peace of mind.

Symptoms That Indicate This Test

Consider the HBsAg Test if you experience:

✅ For Acute Hepatitis B:

• Fatigue, weakness, or malaise
• Jaundice (yellow skin/eyes)
• Dark urine or pale stools
• Abdominal pain (upper right side)
• Nausea, vomiting, loss of appetite
• Low-grade fever or joint pain

✅ For High-Risk Individuals:

• Unprotected sex or multiple partners
• IV drug use or tattoo/piercing with unsterile equipment
• Dialysis or blood transfusion recipients
• Healthcare workers with needle exposure

✅ For Silent Carriers:

• No symptoms but at risk (e.g., family history, endemic region)

Many people are asymptomatic—making screening essential.

Natural Production: How HBsAg Reveals Active Infection

When the Hepatitis B virus (HBV) enters the body:

• It infects liver cells (hepatocytes)
• The virus uses the liver to replicate and produce new viral particles
• HBsAg is released in large amounts into the bloodstream

Key Facts:

• HBsAg appears 1–10 weeks after exposure (average: 4 weeks)
• Positive for 4+ months = likely chronic infection
• Clears in 4–6 months = resolved acute infection
• Chronic carriers (HBsAg+) can transmit the virus even if healthy

Important Notes:

• Vaccination does NOT cause HBsAg positivity
• Only active infection is HBsAg+
• Always confirm with HBV DNA, LFTs, and other markers (HBeAg, anti-HBc)

This test is part of the Hepatitis B Panel for full diagnosis.

What Happens If Untreated? Risks of Ignoring HBsAg Positivity

Ignoring a positive HBsAg result can lead to:

⚠️ Chronic Hepatitis B – lifelong infection in 5–10% of adults, 90% of infants
⚠️ Liver Cirrhosis – scarring and loss of function
⚠️ Liver Failure – requiring transplant
⚠️ Hepatocellular Carcinoma (HCC) – primary liver cancer
⚠️ Mother-to-Child Transmission – 90% risk without intervention

The good news? Hepatitis B is preventable and treatable with:

• Vaccination (3-dose series)
• Antivirals (tenofovir, entecavir) for chronic cases
• HBIG + vaccine for newborns of infected mothers

Early testing = prevention of liver damage and transmission.

How to Prepare for the Test

To ensure accurate results:

✅ No fasting required
✅ Continue your regular medications—but inform your doctor
✅ Inform your doctor of:

• Exposure history (sexual, needle, blood)
• Vaccination status
• Current symptoms or liver disease

A serum blood sample is collected via standard draw—available at our labs or via home collection.

Test Overview: Chemiluminescence Method

Interpretation:

• Negative → No active infection (but may need full panel if at risk)
• Positive → Active HBV infection (further testing required)
• Reactive → Confirm with neutralization test to rule out false positives

Results are reported with clinical notes for your physician.
