Answer

The BD ProbeTec TV Qx Amplified DNA Assay is a DNA-amplification test developed for the BD Viper system, a proprietary automated platform capable of testing for T vaginalis, Chlamydia trachomatis, N gonorrhoeae, HSV-1, and HSV-2. [83] Sensitivity for the assay using self-collected vaginal swabs is 98.3% and specificity is 99%, compared with a composite reference standard of wet mount microscopy and culture. [78] The system can run 96 samples per batch. [83] An independent evaluation of the system found that samples can be run with between 78.7 and 81.2 minutes of total processing time and only 29.8 and 34.2 minutes of “hands-on” laboratory work.
