Laboratory Testing for Hepatitis B



Serologic Markers

Slide 6

June 2008

Next we will review the serologic markers. As I mentioned, the Hepatitis B surface antigen is a reflection of acute or chronic infection. The Hepatitis B surface antibody, which can be measured qualitatively or quantitatively, is a reflection of either recent or past infection, but is also present in successful immunity resulting from Hepatitis B immunization.

Hepatitis B core IgM antibody is only present during the acute infection, but the Hepatitis B core total antibodies are present in both acute and past infection.

Hepatitis B E antigen is present in chronic carriers with active viral replication whereas the Hepatitis B E antibody is present in either chronic carriers with minimal viral replication or those with past infection.
