ANTI HEPATITIS B SURFACE ANTIGEN – TOTAL

The anti-hepatitis B surface antigen (anti-HBs) total test measures the presence of antibodies against the hepatitis B surface antigen. This test is used to determine whether an individual has developed immunity to hepatitis B, either through vaccination or recovery from a past infection. A positive result indicates that the person is protected against hepatitis B infection. The anti-HBs test is crucial for evaluating the effectiveness of hepatitis B vaccination, assessing immunity status, and guiding public health interventions to prevent the spread of hepatitis B. It helps ensure individuals at risk are adequately protected against the virus.
