Also Known As:
Hepatitis B Titre

Anti HBsAb Total
About This Test
Anti HBs appears after HBsAg disappears and persists thereafter. It is rarely detected in the presence of HBsAg in patients with acute Hepatitis B , but 10-20% of patients with chronic Hepatitis B may show low levels of Anti HBs. Presence of Anti HBs has been shown to be important in protection against HBV infection. Passively acquired antibody to HBV as in the case of blood transfusion and recent immunoglobulin therapy does not signify immunity.

TAT Policy
The Turnaround Time (TAT) depends on the following factors:

- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
