Background The AmpliVue Trichomonas Assay (Quidel) is a new Federal Drug Administration-cleared rapid test for qualitative detection of Trichomonas vaginalis (TV) DNA in female vaginal specimens. The assay is based on BioHelix's helicase-dependent amplification isothermal technology in conjunction with a disposable lateral-flow detection device, with a total turnaround time of approximately 45 minutes. Objective The objective of this study was to compare the performance of this new assay to wet preparation and culture as well as to another Federal Drug Administration-cleared nucleic acid amplification assay. Methods Four clinician collected vaginal swabs were obtained from women attending sexually transmitted disease, family planning, and OB/GYN clinics and tested by AmpliVue Trichomonas Assay and comparator tests: saline microscopy, TV culture (InPouch), and Aptima TV. AmpliVue Trichomonas Assay results were compared with a composite positive comparator (CPC) as determined by the results from culture and/or wet mount microscopic examination. At least one of either the wet preparation or culture reference test results was required to be positive to establish CPC. Results A total of 992 patients, 342 symptomatic and 650 asymptomatic patients, were included in the study. Results for AmpliVue for all women combined compared with saline microscopy and culture as a CPC yielded a sensitivity of 100%. Specificity for all women was 98.2%. Overall percent agreement versus Aptima TV was 97.8%. Sensitivity for AmpliVue compared with Aptima was 90.7% %, whereas specificity was 98.9%. Conclusions The rapid AmpliVue Trichomonas Assay performed as well as microscopy and culture, and had comparable sensitivity and specificity to another nucleic acid amplification test for the detection of TV. This study provided evidence of new diagnostic options and indicated very good performance of amplified testing for detection of TV in symptomatic and asymptomatic women.
