Obstet Gynecol 2017.Ī single investigational test swab was used by the patient to self-collect a vaginal specimen in the clinic and then placed in a sheath and handed to the clinician (first collected swab at nine clinical sites and last collected swab at one site). TV, trichomonas vaginalis KOH, potassium hydroxide. Blue boxes indicate patient- or clinician-collected swabs, green boxes refer to specimen transport, and pink boxes refer to testing of the different methods. Eligible specimens meeting study inclusion criteria were included in the sensitivity, specificity, and prevalence calculations ( Appendix 1, available online at ). After written informed consent to clinical research, vaginal discharge specimens were collected between May and September 2015. Before giving informed consent, each patient reviewed the study procedures, risks, and benefits.

The clinical centers were either academic medical center clinics or community clinics.

Exclusion criterion was if they were previously enrolled in this study. At ten clinical centers, all eligible patients were recruited consecutively from clinics identified as sexually transmitted diseases, human immunodeficiency virus, family planning, and gynecology if they reported symptoms of vaginitis (at least one of the following symptoms: abnormal vaginal discharge, painful or frequent urination, vaginal itching or burning or irritation, painful or uncomfortable intercourse, vaginal odor) and enrolled if they provided informed consent and met the minimum age required by their institutional review board (18 at nine sites, and 14 at one site). The study design was a diagnostic accuracy cross-sectional study ( Fig. Comparisons for self-collection were made to demonstrate accuracy could be maintained if self-collection was used for busy clinicians to save time. 18 The study objectives were to compare the investigational molecular test with three reference methods for the diagnosis of vaginitis and compare clinician-collected swabs with self-collected swabs. 16, 17 A single molecular test with high sensitivity and specificity might provide a clinical benefit. Inaccurate test results are problematic for treatment efficacy (Carr FL, Thabault P, Levenson S, Friedman RH. 7, 13 Vaginal swab Gram stain with estimates of numbers of microbial flora is an alternative method for the diagnosis of bacterial vaginosis. 13ĭiagnosis of vaginitis is usually made by clinical findings, wet mount, Amsel criteria, or laboratory tests.

1 The Centers for Disease Control and Prevention recommends use of molecular tests for diagnosis. Trichomoniasis is the most common curable sexually transmitted infection in the world. 7– 9 Candida albicans is responsible for 65–90% of vaginal Candida species infections, and non-albicans Candida species are responsible for up to 30%. In bacterial vaginosis, lactobacilli are decreased, with increases in microorganisms such as Atopobium vaginae, Gardnerella vaginalis, Mobiluncus mulieris, Prevotella species, BVAB-2, and Megasphaera species. 4, 5 Lactobacillus crispatus and Lactobacillus jensenii are common lactobacilli in the vaginas of healthy women. Lactobacilli have predominant roles in the commensal vaginal flora by producing lactic acid. 2 In a review of symptomatic women, bacterial vaginosis was diagnosed in 22–50%, vulvovaginal candidiasis in 17–39%, and trichomoniasis in 4–35%. 1 The main diagnoses are bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis. Symptomatic vaginitis accounts for millions of clinical visits annually. Vaginitis is a common problem for women associated with discomfort.
