HBsAg test is a blood test that detects hepatitis B surface antigen (HBsAg). HBsAb is a protein on the surface of the hepatitis B virus. High levels of HBsAg typically indicate an active hepatitis B virus infection. HBsAg is a part of the outer layer of a hepatitis B virus cell. The center of the cell contains the viral DNA

How our test process works!
Overview:
- Test Name: Hepatitis B Surface Antigen Quantitative (HBsAgQ2)
- Purpose: Measures the amount of Hepatitis B surface antigen in the blood to diagnose and monitor chronic Hepatitis B infection and assess treatment response.
Risk Assessment:
- Risk Factors for Hepatitis B Infection:
- Unprotected sexual contact
- Intravenous drug use (sharing needles)
- Vertical transmission (mother to child during birth)
- Occupational exposure (e.g., healthcare workers)
- Blood transfusions (rare in modern settings due to screening).
Normal Range:
- Quantitative HBsAg:
- Negative: <0.05 IU/mL or "non-reactive" (varies by laboratory).
- Positive: Detectable levels indicating active infection or carrier state.
Interpretation:
-
Negative Result:
- No active Hepatitis B infection.
- May indicate resolved infection or successful vaccination.
-
Positive Result:
- Low Levels: Chronic inactive carrier or resolving infection.
- High Levels: Active chronic Hepatitis B infection or acute infection phase.
- Used alongside HBV DNA levels for monitoring disease progression or treatment effectiveness.
-
Borderline/Equivocal: Repeat testing may be required for confirmation.
Sample Type:
- Specimen: Serum or plasma
- Collection: Blood sample (typically drawn from a vein in the arm).
- Volume: Approximately 2–3 mL.
