Abstract:
:Panels of hepatitis B virus surface antigen-positive sera from drug abusers were used to evaluate 14 commercial enzyme immunoassays from six companies for detecting hepatitis delta virus (HDV) markers. For detecting hepatitis delta virus antigen (HDAg), the Wellcome, Pasteur and Noctech assays had 100% sensitivity for all 42 HDAg-positive serum specimens that were confirmed in-house; the Organon reagents gave 59.5% sensitivity without detergent and 64.3% sensitivity with detergent, but there were 14 discrepant results with and without detergent. The Sorin assay detected HDAg in only 10 of the positive samples (23.8% sensitivity). For the detection of antibody to HDV (anti-HDV) all six commercial enzyme immunoassays were reactive with all 36 anti-HDV-positive specimens that were confirmed in-house. There were no false-positive results with the Wellcome, Noctech, or Sorin assay, but one specimen was false positive by the Organon assay. One HDAg-positive specimen gave a false anti-HDV-positive result in the Abbott assay and an equivocal result in the Pasteur assay (97.8% specificity). For the detection of immunoglobulin M anti-HDV, the Wellcome, Noctech, and Sorin assays agreed for the 38 positives confirmed in-house, except for one false negative with the Sorin test. We conclude that there has been a substantial improvement over previously evaluated assays in sensitivity and specificity of commercial assays for anti-HDV detection, and the sensitivities of immunoglobulin M anti-HDV assays are also comparable. However, there are still major differences in sensitivity among some assays for HDAg detection.
