   Sensitivity and specificity for detection of candidiasis in symptomatic women: 82% and 95%, respectively.

   Sensitivity and specificity for detection of BV in symptomatic women: 98% and 100%, respectively.

   Sensitivity and specificity for detection of trichomoniasis, compared to wet mount detection: 93% and 99%, respectively.

   
Turnaround time:
24 hours.

   Specimen Collection and Transport Instructions

   Vaginal fluid specimens should be collected only from patients with symptoms consistent with vaginosis or vaginitis.

   Use only supplies provided in the Affirm VPIII transport system, sample collection set, or test kit for specimen collection.

   Samples are collected from the posterior vaginal fornix, using an unlubricated (no water or jelly) speculum, ensuring that the entire circumference of the swab has been inoculated with vaginal secretions.

   Place the swab into sample collection tube and snap on cap following the kit instructions.

   Transport specimens according to kit instructions. Specimens may be transported at room temperature or refrigerated.

   Interpretation

   
Expected results:
Negative for all three pathogens. Negative results for a specific pathogen suggest that infection with that pathogen is unlikely.

   
Positive results:
If one or more of the pathogens tested indicate infection when consistent signs and symptoms are present. Infection with more than one of the pathogens is not uncommon.
