Interpretation This test is most useful to document chronic active hepatitis B in patients who are surface antibody negative and indicates past infection with hepatitis B in patients who are surface antigen negative. This test is performed if past infection with hepatitis B is suspected in an asymptomatic patient, Hep B Surface Antibody is the first choice, followed by Hepatitis B Core Total Antibody to identify patients who do not have detectable surface antibody. If acute Hepatitis B is suspected, Hep B Core IGM (see previous test) should be ordered.
