Vaginitis Plus (VG+), NuSwab®

Methodology: 
Nucleic acid amplification (NAA)
Performed: 
Monday - Friday
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, and Megasphaera-1) to generate a total score that correlates directly with the presence or absence of BV. In this test system, samples with a total score of 0 to 1 are considered negative for BV, samples with a score of 3 to 6 are positive for BV, and samples with a score of 2 are indeterminate for BV. 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. Also used in the diagnosis of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infections.
