A trichomoniasis test checks for infection with Trichomonas vaginalis, a common sexually transmitted parasite. It is ordered when someone has symptoms like vaginal discharge or genital irritation, or after possible exposure.
What it measures
- Trichomonas vaginalis DNA — Genetic material from the parasite; a positive result means the infection is present.
- Trichomonas vaginalis RNA — Another genetic marker; used by some tests to detect active infection.
- Antibodies to Trichomonas vaginalis — Immune proteins that can show past or current exposure, though not always used.
Who it is for
Healthcare providers typically order this test for anyone with symptoms of trichomoniasis or for people at higher risk, such as those with multiple sex partners or other STIs.
Preparation
No fasting or special preparation is needed. You can eat, drink, and take medications as usual before the blood draw.
Results and what they mean
Results are usually reported as positive (infection detected) or negative (not detected), sometimes with a numerical value. A clinician interprets the result along with your symptoms and history.
