Test ID: HBIM Hepatitis B Core Antibody, IgM, Serum

Reporting Name

HBc IgM Ab, S

Useful For

Diagnosis of acute hepatitis B virus (HBV) infection

 

Identifying acute HBV infection in the serologic window period when hepatitis B surface antigen and anti-hepatitis B surface are negative

 

Differentiation between acute and chronic or past HBV infections in the presence of positive anti-hepatitis B core

Clinical Information

Hepatitis B virus (HBV) is a DNA virus that is endemic throughout the world. In the initial (acute) phase of infection, hepatitis B core antibodies (anti-HBc) consist almost entirely of the IgM antibody class and appear shortly after the onset of symptoms. Anti-HBc IgM can be detected in serum and is usually present for up to 6 months after acute HBV infection. Anti-HBc IgM may be the only serologic marker of a recent hepatitis B infection detectable following the disappearance of hepatitis B surface antigen and prior to the appearance of hepatitis B surface antibody (ie, serologic window period).

 

See Viral Hepatitis Serologic Profiles

Interpretation

A positive result indicates recent acute hepatitis B infection.

 

A negative result suggests lack of recent exposure to the virus in preceding 6 months.
