Frequently Asked Questions

What does HBsAg test detect?

HBsAg detects the surface protein of the Hepatitis B virus in blood, indicating an active current infection — either acute or chronic.

Is fasting required for HBsAg test?

No, fasting is not required. The test can be performed on a non-fasting sample at any time of day.

What does a reactive HBsAg result mean?

A reactive (positive) result indicates active Hepatitis B infection. Further testing for HBeAg, anti-HBc IgM, and HBV DNA is recommended to determine acute vs chronic status.

How long does it take to get the report?

Verified PDF report is available within 24 hours via www.drpatholab.in or WhatsApp/Email.

Can HBsAg be negative during early infection?

Yes, there is a window period of 2–8 weeks after exposure when HBsAg may not yet be detectable. Repeat testing after 4–6 weeks is advised if exposure is suspected.

Does this test determine immunity to Hepatitis B?

No, HBsAg only detects active infection. Immunity is assessed through Anti-HBs (Hepatitis B Surface Antibody) testing, which indicates protection from vaccination or past resolved infection.
