Method Description

This test is performed using a competitive enzyme immunoassay in which hepatitis delta virus-specific antibodies (anti-HDV) compete with virus-specific polyclonal IgG antibody that is labeled with peroxidase (HRP) for a fixed amount of recombinant HDV protein coated on the microplate wells. Patient serum sample is added first to the microplate well, in which anti-HDV IgG and IgM antibodies will bind to the recombinant HDV protein coated in the well. After washing, a polyclonal anti-HDV-enzyme conjugate is added and allowed to bind to unbound recombinant HDV protein. After another wash, a chromogenic mixture is added as a substrate for the HRP enzymatic reaction. Concentration of the enzyme conjugate bound to the coated well is inversely proportional to the amount of HDV total antibodies present in the patient sample. The concentration of HDV total antibodies present is determined by comparing the calorimetric reaction signal to a calibrated cut-off signal value.(Package insert: HDV Ab, Rev.4 0115; International Immuno Diagnostics, Foster City, CA 94404 01/2015)
