Hepatitis B Core Antibody, Total

Test Code: 501

CPT Code(s): 86704

Methodology: Immunoassay (IA)

Clinical Significance: This assay does not distinguish between Total B core antibody IgG and IgM detected before or at the onset of symptoms; however, such reactivity can persist for years after illness, and may even outlast anti-HBs. Occasionally Hepatitis B core antibody may be the only marker of either current or past Hepatitis B infection.

Alternative Name(s): Anti-HBC; B Core; Core Ab; Corzyme; Hep B Core Ab
