DNA Probe.The AFFIRM microbial vaginitis test identifies the three most common causes of infectious vaginitis (Candida species, Gardnerella vaginalis, and Trichomonas vaginalis) utilizing the FDA approved nucleic acid probe technology by Becton Dickinson. Test performance characteristics of the assay are as follows per the Becton Dickinson kit insert: Sensitivity: Relative to Microscopy: Gardnerella vaginalis - Trichomonas vaginalis - 95% 93% Relative to Culture: Specificity: Candida species - 82% Gardnerella vaginalis - Trichomonas vaginalis - 98% 90% Relative to Microscopy: Gardnerella vaginalis - Trichomonas vaginalis - 100% 99.9% Relative to Culture: Candida species - 98.4% Gardnerella vaginalis - Trichomonas vaginalis - 100% 99.9% Although highly sensitive and specific, if test results aren't consistent with clinical presentation, additional testing by other methods may be warranted. YourSwab™ (BD ESwab) was validated by Pathology, Inc. as an acceptable alternate collection device.
