New latex agglutination test for rapid determination of rubella immune status.

A prototype rubella latex agglutination card assay (Hynson, Westcott and Dunning, Baltimore, Md.) was compared with a standard hemagglutination inhibition test for the detection of rubella antibodies in 500 sera. The sensitivity and specificity of the latex agglutination assay were 100% and 94%, respectively. This assay did not require pretreatment of serum, and the entire assay could be performed in 10 min.
