Comparative evaluation of commercial rubella virus antibody kits

Comparative evaluation of six commercial rubella virus antibody kits is described. A set of serum samples skewed toward nonreactive and low-positive rubella antibody levels was used because the goal of an immunity screening test is the detection of susceptible individuals. The M. A. Bioproducts Rubastat and the Hynson, Westcott and Dunning Rubascan were superior in achieving high sensitivity, specificity, and reproducibility. They also were the easiest and fastest tests to perform, and they require equipment available in most laboratories.
