How does a trichomoniasis test work? 

How does a trichomoniasis test work? Let’s run through the different types of testing for trichomoniasis, as well as where you can purchase a trichomoniasis test.

Trichomoniasis is a sexually transmitted disease caused by a parasite called trichomonas vaginalis (TV), which passes from an infected person to another during sex. Trichomoniasis is passed through the exchange of fluids from the vagina and the penis from one infected person to the other.

Trichomoniasis most commonly affects the: 

  • Vulva
  • Vagina
  • Cervix
  • Urethra 

How does a trichomoniasis test work? 

A trichomoniasis test may require a urine or genital swab collection sample.

According to Mayo Clinic, trichomoniasis can be diagnosed by looking at a sample of vaginal fluid for women or urine for men under a microscope. 

If the parasite can be seen under the microscope, no further tests are needed. If this test isn’t conclusive, more sensitive tests called rapid antigen tests and nucleic acid amplification may be used.

How do you get trichomoniasis if your partner doesn’t have it? 

Trichomoniasis is most commonly contracted through having unprotected sex with an infected partner. 

If you receive a diagnosis for trichomoniasis, there are a couple of possible explanations. 

The symptoms of trichomoniasis can remain dormant for weeks which means that: 

  • Your partner could have contracted trichomoniasis in a previous sexual relationship.
  • You could have contracted trichomoniasis in a previous sexual relationship but are only experiencing the symptoms now. 

Does trichomoniasis have a smell?

Trichomoniasis may produce a foul fishy smell in women. 

What does trichomoniasis look like? 

Trichomoniasis doesn’t have a definitive aesthetic appearance, however it can lead to swelling and redness in both male and female genitals. 

Can you get rid of trichomoniasis? 

Trichomoniasis is usually treated with a single dose of prescription antibiotic medication (either metronidazole or tinidazole), pills which can be taken by mouth. It is okay for pregnant women to take this medication.
