Diagnostic rates differ on the basis of the number of read days with the use of the InPouch culture system for Trichomonas vaginalis screening

The InPouch Trichomonas vaginalis test is the gold standard for clinical culture for Trichomonas vaginalis screening. The current package insert recommends an examination period of 3 days. After review of 2,499 InPouch tests spanning 13 years, we observed that examination up to 3 days will detect only 82.8% (95% confidence interval [CI], 79.0% to 86.2%) of positive specimens.
