Comparison of a new, rapid enzyme immunoassay with a latex agglutination test for qualitative detection of rubella antibodies.

A total of 450 sera were tested for rubella virus antibodies by using a new, rapid enzyme immunoassay, SUDS Rubella. The results were compared with those obtained by using the Rubascan test, a well-established latex agglutination method. The sensitivity of the SUDS Rubella was 99.5%, and the specificity was 100%, when compared with Rubascan. The SUDS Rubella test can be performed in 10 min and provides an accurate screening test for the detection of rubella antibodies.
