[Detection of IgG antibodies against rubella virus using the "Rubella-IgG-EIA SSW" test kit]

A new commercial ELISA test kit "Rubella-IgG-EIA SSW" is described for the determination of IgG antibodies to rubella virus. A panel of 99 sera was tested by "Rubella-IgG-EIA SSW" and by hemagglutination-inhibition (HI test). The results of enzyme-immunoassay (EIA) and of HI test correlate well; the coefficient of correlation is 0.95, the specificity is 90.9% and the sensitivity is 100%. A coefficient of correlation was found out of 0.92 between EIA and HI test in the evaluation of the quantitative procedure. The test kit can be used for determination of immune status to rubella virus and for quantitative detection of rubella-IgG antibodies.
