[Indirect ultramicroElisa for the detection of total antibodies against cytomegaloviruses in human blood].
We have standardized an indirect ultramicro ELISA assay for detecting antibodies to human Cytomegalovirus (CMV) using human serum samples (UMELISA CMV). The optimal concentration of coating antigen (30 ug/ml), serum dilution (1:40) and anti-human conjugate working dilution (1:1500), were determined by a check board titration method. The UMELISA CMV was compared with the latex agglutination test for antibodies to CMV (Dupont de Nemours) and with an indirect immunofluorescent method. The results have showed the high coincidence, sensitivity and especificity of the proposed assay regarding the two methods compared with, and supporting its use either for a blood donors screening or in the serological diagnosis of this infection by paired serum samples.
