Test Code: 4848

CPT Code(s): 86705

Methodology: Immunoassay (IA)

Clinical Significance: Hepatitis B core-specific IgM class antibody has been detected in most acute infections and is a reliable marker for acute disease. In some cases, hepatitis B core IgM antibody may be the only specific marker for the diagnosis of acute infection with hepatitis B virus.

Alternative Name(s): Anti-HBc, IgM

Test Code: 512

CPT Code(s): 86709

Methodology: Immunoassay (IA)

Clinical Significance: IgM antibodies to Hepatitis A suggest a current, acute or recent Hepatitis A infection.

Alternative Name(s): Hep A IgM; Acute Hep A; Anti-HAV IgM; HAV IgM

Test Code: 508

CPT Code(s): 86708

Methodology: Immunoassay (IA)

Clinical Significance: HAV antibody indicates prior or acute infection with, or immunization to, Hepatitis A virus.

Alternative Name(s): HAV Total,HAV Antibody

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.
