Performance Study of the Cobas® BV/CV Test on Samples From Participants With and Without Symptoms of Bacterial Vaginosis and Candida Vaginitis

Completed

Conditions studied: Bacterial Vaginosis, Candida Vaginitis

In brief

In the clinical performance part of this study, prospectively acquired clinician-collected and clinician-instructed, self-collected vaginal swab specimens collected in cobas® PCR Media will be taken from a minimum of 500 symptomatic individuals with a clinical presentation consistent with vaginitis, vaginosis, or both. Additionally, a minimum of 100 asymptomatic individuals will also be enrolled in the study. The cobas® BV/CV assay amplifies and detects the deoxyribonucleic acid (DNA) of pathogens associated with bacterial vaginosis (BV) and candida vaginitis (CV). The BV results will be compared with the patient infection status (PIS) established by using 3 Food and Drug Administration (FDA)-cleared commercial assays, and the CV results will be compared with the PIS established with the use of culture plus MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight). The primary objective of the clinical performance study is to evaluate the performance (sensitivity and specificity) of cobas® BV/CV to determine the presence of BV and/or CV in the intended use patient population when being tested on cobas® 6800/8800 systems. The secondary objective is to evaluate the equivalency of cobas® BV/CV between the cobas® 5800 system and cobas® 6800/8800 systems.
