Bacterial Vaginosis and Candida, NAA, NuSwab®
Use
This test is intended to be used as an aid to the diagnosis of bacterial vaginosis (BV) in women with a clinical presentation consistent with this disorder. The BV test utilizes semiquantitative PCR analysis of the three most predictive marker organisms (Atopobium vaginae, BVAB-2, Megasphaera-1) to generate a total score that correlates directly with the presence or absence of BV. It is also used to detect the presence of Candida albicans and Candida glabrata DNA in vaginal samples as an aid to the diagnosis of vulvovaginal candidiasis in symptomatic women.
Special Instructions
Optimal specimen collection involves using the Aptima® swab to collect vaginal fluid sample from the lower third of the vaginal wall, rotating the swab for 10 to 30 seconds, then placing the swab into the transport tube and breaking the swab shaft against the side of the tube, followed by tightly screwing on the cap.
Limitations
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. Specimens received frozen, leaking during transit, with inappropriate source for test requested, or in expired transport are among causes for rejection.
