Rapid detection of vaginal colonization with group B streptococci by means of latex agglutination.

Latex agglutination testing for colonization of the vagina with group B streptococci was carried out in 1100 patients. Samples underwent latex testing after 8 to 12 hours of preincubation in selective growth medium. This technique allowed a sensitivity of 91.8% and specificity of 97.6%. This study demonstrates the usefulness of latex agglutination testing in the detection of vaginal colonization with group B streptococci.
