What kind of test is required for Hepatitis B?

The correct choice is based on the standard procedure to test for Hepatitis B, which typically involves a three-step process. This three-step testing method allows healthcare providers to accurately determine the presence and stage of the Hepatitis B virus by testing for different markers in the blood.

The initial step generally includes screening for the Hepatitis B surface antigen (HBsAg), which indicates an ongoing infection. If this test is positive, further testing is done, typically involving a second step to check for the Hepatitis B e antigen (HBeAg) and potentially an antibody test to assess immunity or past infections. The third step might involve additional tests that help to outline the individual's immune response or the viral load.

In contrast, the other options listed suggest testing procedures that are not aligned with standard medical guidelines or practices for Hepatitis B. These are not recognized as valid protocols for evaluating Hepatitis B status and do not align with the established medical testing framework. Thus, the three-step test is acknowledged as the appropriate procedure for accurate diagnosis and management of Hepatitis B.
