HEPATITIS B CORE ANTIBODY IGM(ANTI HBC-IGM) ELISA Test

The Hepatitis B Core Antibody IgM (Anti-HBc IgM) – ELISA test detects IgM antibodies produced against the core antigen of the hepatitis B virus (HBV).

This test is primarily used to help identify a recent or acute hepatitis B infection. Anti-HBc IgM may appear during the early phase of infection and can also be present during some flare-ups or reactivation of chronic hepatitis B.

The result is generally interpreted along with other hepatitis B markers, such as HBsAg, Anti-HBs, and total Anti-HBc, as well as liver function tests and clinical findings.

Test Recommended for Individuals:

• Individuals with symptoms suggestive of acute hepatitis B
• People with recent or suspected exposure to HBV
• Individuals with unexplained elevation of liver enzymes
• Patients undergoing evaluation for suspected hepatitis B infection
• Individuals with hepatitis B test results that require further clarification
• People being evaluated for possible recent HBV infection
• Patients advised by their healthcare provider to undergo hepatitis B testing

FAQs

1. What does a positive Anti-HBc IgM result mean?
A positive Anti-HBc IgM result generally indicates a recent or acute hepatitis B infection. It may also be detected during certain episodes of chronic hepatitis B reactivation, so the result should be interpreted with other HBV markers.

2. Is Anti-HBc IgM the same as the hepatitis B surface antigen test?
No. Anti-HBc IgM detects antibodies against the hepatitis B core antigen, whereas HBsAg detects hepatitis B surface antigen. These tests provide different information and are often interpreted together.

3. Can Anti-HBc IgM be positive during the window period of hepatitis B?
Yes. Anti-HBc IgM can remain detectable during the period when HBsAg may have disappeared but Anti-HBs has not yet become detectable, commonly referred to as the window period. Your healthcare provider may recommend a complete hepatitis B panel for accurate interpretation.
