Hepatitis B Virus Core IgM Antibody (HBc IgM)
The HBc IgM assay is an IgM capture immunoassay that uses a 2-step format to identify antibody-antigen complexes that are formed if HBV is present.
This test is used to determine active infection to HBV by looking for antibodies to the viral central core and surrounding envelope.
