What are the results of hepatitis b profile?

The results of a hepatitis B profile typically include the following:

Hepatitis B surface antigen (HBsAg): This test detects the presence of HBsAg, which is a protein found on the surface of the hepatitis B virus. A positive HBsAg test indicates that the person is currently infected with the hepatitis B virus.

Hepatitis B surface antibody (anti-HBs): This test detects the presence of anti-HBs, which is an antibody that is produced by the body in response to infection with the hepatitis B virus. A positive anti-HBs test indicates that the person has had a hepatitis B infection in the past and is now immune to the virus.

Hepatitis B core antibody (anti-HBc): This test detects the presence of anti-HBc, which is an antibody that is produced by the body in response to infection with the hepatitis B virus. A positive anti-HBc test indicates that the person has had a hepatitis B infection in the past, but may or may not be immune to the virus.

Hepatitis B e antigen (HBeAg): This test detects the presence of HBeAg, which is a protein that is produced by the hepatitis B virus. A positive HBeAg test indicates that the person is currently infected with the hepatitis B virus and is highly contagious.

Hepatitis B virus DNA: This test detects the presence of hepatitis B virus DNA in the blood. A positive hepatitis B virus DNA test indicates that the person is currently infected with the hepatitis B virus.

The results of a hepatitis B profile can be used to diagnose hepatitis B infection, determine the stage of infection, and assess the risk of transmission.
