Quick Answer

Testing for trichomoniasis usually involves a nucleic acid amplification test (NAAT) on a urine sample or vaginal swab, which is highly accurate. A wet mount microscopy test may also be used but is less sensitive. Results are typically available within a few days, and treatment with metronidazole or tinidazole is effective.

  • NAAT is the most sensitive test for trichomoniasis, detecting the parasite's genetic material.
  • Wet mount microscopy is quick but can miss up to 40% of infections.
  • Testing is recommended for anyone with symptoms or who has had unprotected sex.
  • Trichomoniasis can be detected from a urine sample or a vaginal or penile swab.
  • A positive result means the parasite is present and treatment is needed.
  • A negative result may require repeat testing if symptoms continue.

The Short Version, Structured

Trichomoniasis is a common sexually transmitted infection caused by the parasite Trichomonas vaginalis. Many people with the infection have no symptoms, which means they can unknowingly pass it to partners. Without treatment, trichomoniasis can increase the risk of other STIs and, in pregnant women, lead to preterm delivery. Testing is the only reliable way to know if you have the infection, and it guides effective treatment with prescription medication. Understanding the different test options, when to test, and what results mean helps you take control of your sexual health.
