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

Test Code: 499

CPT Code(s): 86706

Methodology: Immunoassay (IA)

Clinical Significance: The detection of anti-HBs is indicative of a prior immunologic exposure to the antigen or vaccine. To determine immune status as ≥10 mIU/mL as per CDC guidelines, please order Hepatitis B Surface Antibody, Quantitative.

Alternative Name(s): Anti-HBS; Anti-HBS Qual; Anti-HBSAG; Australian Antibody; HB Surface Ab
