Abstract:
:A normalized enzyme-linked immunosorbent assay for the determination of immunoglobulin G antibodies to cytomegalovirus is described. The rapid assay involves three 30-min incubations and permits the quantitation of antibody levels with a single-specimen dilution in conjunction with a reference antibody preparation. The results obtained with the normalized enzyme-linked immunosorbent assay correlated closely with the results of complement fixation titrations and another commercially available enzyme-linked immunosorbent assay. The specificity of the procedure was further demonstrated by viral absorption, using cytomegalovirus from two different sources and other viral antigen preparations, including rubella and influenza. The reproducibility of the normalized test results is good and allows for greater uniformity of reporting on a day-to-day basis, as well as between laboratories.
