Hepatitis D Virus (HDV) Total Antibody

Test Code: 99202

Cpt Code:

86692 (x1)

Clinical Utility

Hepatitis D virus (HDV) is an incomplete RNA virus that requires the helper function of Hepatitis B virus (HBV) envelope proteins (HBSAg) to replicate. The presence of HDV antibodies indicates exposure to HDV, but does not distinguish acute or chronic HDV infection. Typically the disappearance of HDV antibodies is indicative of resolution of infection. The assay method is a competitive ELISA utilizing recombinant HDV antigen.

Procedure

The HDV total antibody ELISA is a competitive immunoassay. Anti-HDV antibodies, if present, compete with HRP-conjugated polyclonal anti-HDV antibodies for recombinant HDV antigen adsorbed to the microtiter plate. This test was developed and its performance characteristics determined by Viracor-IBT Laboratories. It has not been cleared or approved by the U.S. Food and Drug Administration. Results should be used in conjunction with clinical findings, and should not form the sole basis for a diagnosis or treatment decision.
