Trichomoniasis Test

Trichomoniasis Test

Trichomoniasis is a sexually transmitted infection that affects both men and women. It is caused by a protozoan parasite called Trichomonas vaginalis. The infection is more common among women than men and can cause irritation, inflammation, and discharge of the vagina and penis. A trichomoniasis test is used to diagnose the infection.

Preparation for the Test

In preparation for the test, patients should provide a sample of body fluid. The sample may be taken from the penis, urethra, or vagina, depending on the sex of the patient. The sample will be sent to a laboratory for analysis.


The lab technician will use a microscope to look for the presence of Trichomonas vaginalis. The organism will appear as small, oval-shaped, and have four flagella. If the presence of the parasite is confirmed, a positive result will be reported.


There are two types of tests used to diagnose trichomoniasis. The first is a wet mount test, which involves looking for the organism by examining a sample of the patient's body fluid under a microscope. The second is a PCR test that screens for the presence of genetic material of the parasite.


The test is relatively safe and poses no risks to the patient. The only risk is a false-positive result, which can occur if the sample contains other organisms that resemble the Trichomonas vaginalis.

Why Is The Test Performed?

The test is performed to diagnose trichomoniasis, which can cause irritation, inflammation, and discharge of the vagina and penis. If left untreated, the infection can lead to pelvic inflammatory disease in women, and urethritis and epididymitis in men.

When Is the Test Performed?

The test is usually performed when a person has symptoms of trichomoniasis, such as irritation, inflammation, or discharge of the vagina or penis. The test is also performed if a person has had unprotected sex with someone who has the infection.
