Trichomoniasis testing checks for infection by the parasite Trichomonas vaginalis. It is a sexually transmitted infection that can affect the vagina, urethra, or prostate and often causes no symptoms at all. Testing is usually done with a urine sample or a genital swab, using nucleic acid amplification testing to detect the parasite's genetic material. It may be ordered for people with discharge, irritation, or burning, or as part of routine sexual health screening. Detecting it helps prevent spread to partners and supports appropriate care.

• Trichomonas vaginalis NAAT Detects the parasite's genetic material in urine or a genital swab.
• Trichomonas vaginalis antigen Identifies parasite proteins, often from a swab sample.
• Microscopy Directly visualizes the parasite under a microscope, though it is less sensitive than molecular testing.

• People with unusual discharge, irritation, or burning during urination
• Anyone requesting a routine sexual health screen
• People whose partner has been diagnosed with Trichomonas vaginalis
• Individuals with persistent urinary or genital symptoms

• No fasting is required.
• Avoid urinating for about one hour before giving a urine sample.
• Avoid vaginal douches or creams before a swab if instructed.
• Tell the collector about antibiotics or antiparasitic medicines you take.

A positive result means Trichomonas vaginalis was detected and should prompt further medical evaluation. A negative result usually means the parasite was not found, but it does not completely rule out infection if exposure was very recent. Because it is a sexually transmitted infection, evaluation of partners is often recommended. Discuss results with a healthcare provider, who can advise on next steps.
