Background: Trichomonas vaginalis [TV] may cause adverse outcomes in pregnancy and better laboratory tests are needed.
Objectives: To determine the prevalence of TV by testing self-collected vaginal swabs [VS] by wet mount [WM] and transcription mediated amplification [TMA] tests using Gen-Probe analyte specific reagents [ASR].
Methods: Group A consisted of 247 women attending a street youth clinic who self-collected 2 VS. The first dacron swab was collected into an M40 tube [
Results: The TV prevalence was 18.2% [45/247] in Group A and 13.5% [39/289] in Group B. The percent sensitivity and specificity in Group A were: ASR-TMA 93.3% [42/45] and 97.5% [197/202] compared to WM which was 20.0% [9/45] and 100% [201/201]: in Group B the values were 92.3% [36/39] and 98.8% [247/250] for AS and 92.3% [36/39] and 99.2% [248/250] for FS.
Conclusions: This TV-TMA test using ASR was easy to perform, yielding clear results with self-collected VS using different swab types. A run of 98 samples was processed in approximately 6 hours. The sensitivity of WM makes it unacceptable.
Implications for Programs, Policy, and/or Research: TV-TMA testing can be performed on self collected VS and should enable more accurate identification and treatment of infections.
