What is this test?

This laboratory test checks for Chlamydia trachomatis, abbreviated CT, and the parasite Trichomonas vaginalis. These infections can affect the vagina, cervix, urethra, or urinary tract and may cause similar symptoms.

Why might I need this test?

The test may be ordered because of symptoms such as unusual vaginal discharge, genital itching, painful urination, or pelvic discomfort. It may also be used during routine screening because CT and Trichomonas infections can occur without noticeable symptoms.

How is the test performed?

A laboratory examines a specimen for evidence of the organisms. Depending on the test and laboratory, the sample may be first-catch urine, vaginal fluid, or a genital swab collected by a clinician.

How do I prepare for the test?

Follow the collection instructions provided by the clinic or laboratory. If a urine sample is requested, collection timing and instructions may matter; do not stop prescribed medicines unless your clinician advises you to do so.

Frequently asked questions

Can these infections cause symptoms?
Yes. Common symptoms include unusual discharge, itching, burning with urination, and pelvic discomfort, but some people have no symptoms.
Does a negative result completely rule out infection?
Usually, but testing can miss an infection, particularly when it is very recent or the specimen was not collected correctly. Your clinician may recommend repeat testing if your risk or symptoms remain concerning.
What should I do if the result is positive?
Contact your clinician promptly for treatment and guidance about sexual partners. Do not use leftover medication or share antibiotics with anyone else.
