Trichomonas Vaginalis (T. vaginalis) Testing

Trichomonas vaginalis is a single cell parasite. This kind of parasite cannot be seen by the naked eye. It cannot only cause vaginal infections in women but also infections of the urethra and inflammation of the prostate in men.



Trichomonas testing detects the parasite in samples from the vagina or penis to diagnose an infection.

  • A positive test indicates an infection with T. vaginalis that requires treatment with prescription medication. If someone is infected, their sexual partner(s) should also be tested and treated as well.
  • A negative test indicates two things. It could be that there is no infection with T. vaginalis and symptoms are due to another cause. And it could also be that the parasite was not able to be detected in the sample using the test method performed. If trichomoniasis is still suspected, a different testing method may be used to confirm the result.
