Abstract：
:An enzyme immunoassay for the detection of IgG and IgM anti-polymerized albumin autoantibodies (AAA) is described. It was found that polyalbumin receptors on HBsAg particles interfere in the detection of IgG AAA when polymerized human albumin (pHSA), but not polymerized bovine albumin (pBSA), is used as coating antigen. Polyalbumin receptors do not appear to interfere in the detection of IgM AAA, with either pHSA or pBSA as coating antigen. All normal sera showed evidence of AAA, of both IgG and IgM classes. Levels of IgG and IgM AAA in sera from most type A and type B acute hepatitis patients were above the range of normal controls. ELISA detection of AAA distinct from HBsAg reactivity can help in understanding the role of these autoantibodies in HBV infection.
