Hepatitis B Core Antibody Test, IgM

The hepatitis B core antibody test, IgM is a blood test that detects the presence of IgM antibodies to the hepatitis B core antigen. IgM antibodies are produced in the early stages of a hepatitis B infection, typically within 1-2 weeks after exposure to the virus.

This test is often used to diagnose acute or recent hepatitis B infection, as well as to monitor the progression of the infection. A positive result indicates an active or recent infection, while a negative result indicates no current infection.

It is important to note that the presence of hepatitis B core antibody, IgM alone is not sufficient for a diagnosis of hepatitis B infection. Additional tests, such as the hepatitis B surface antigen test, are usually needed to confirm the diagnosis.

If you have concerns about hepatitis B infection or are at risk of exposure, it is important to speak to your healthcare provider about getting tested and vaccinated against the virus. Hepatitis B is a serious infection that can cause liver damage and other complications if left untreated.
