Understanding Your Results

Results indicate the level of Hepatitis B Surface Antigen in the blood, helping to diagnose and monitor infection.
A positive result (detectable HBsAg) indicates current Hepatitis B infection, which could be acute or chronic.
A negative result (non-reactive or below cut-off) suggests no current infection, but does not rule out past exposure.
Quantitative levels above the reference range indicate active infection; levels may decrease with successful treatment.
Persistently high levels may indicate chronic infection requiring medical management.
Consult a healthcare provider for interpretation in context of symptoms and other test results.
⚠️ When to Consult a Doctor:

If you experience symptoms of Hepatitis B, have been exposed to the virus, or are on treatment for chronic Hepatitis B and need to monitor your condition.
