Hepatitis D Virus (HDV) IgM

Test Code: 30336

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 IgM antibodies indicates recent exposure to HDV.

Procedure

The Hepatitis D IgM Assay is an enzyme linked capture immunoassay. IgM contained in the sample is captured by monoclonal antibody against human IgM immobilized on the solid phase. Hepatitis D specific IgM is detected with an HRP conjugated HDV antigen complex. Positive samples will have OD values above the established cutoff. 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.

Specificity

The assay is specific for Hepatitis D.

Assay Range

Qualitative: Negative/Equivocal/Positive.

Causes For Rejection

Sample types other than serum and plasma. Samples beyond their stability.

Turnaround Time
