Overview
Laboratory tests used in the diagnosis of trichomoniasis include saline microscopy, culture, and nucleic acid amplification tests (NAATs).[1]
Laboratory Findings
Microscopy
Trichomoniasis is diagnosed by visually observing the trichomonads via a microscope. In women, the examiner collects the specimen during a pelvic examination by inserting a speculum into the vagina and then using a cotton-tipped applicator to collect the sample. The sample is then placed onto a microscopic slide and sent to a laboratory to be analyzed. Trichomoniasis has been difficult to diagnose due to the poor sensitivity of the tests.[2]
