Pelvic Exam
Trich, also known as trichomoniasis, is a vaginal infection that is caused by small parasites called trichomonas vaginalis. This sexually transmitted disease is most commonly identified during a pelvic exam. As Women'sHealth.gov explains, physicians doing a pelvic exam may notice the characteristic small red sores on the inside of the vagina or the cervix (located at the back of the vagina). Physicians can also look for general vaginal redness as well as a foul-smelling discharge which is also characteristic of a trich infection.
Other Tests
More definitive diagnosis of trichomoniasis requires testing beyond a pelvic exam. As the Mayo Clinic explains, the easiest way to confirm the initial suspicion of trichomoniasis is to examine a sample of vaginal fluid under a microscope. If the fluid sample is kept warm, the parasites can be seen swimming around in the vaginal fluid. Other tests, such as a Pap smear, can also potentially diagnose a trichomonas infection. WomensHealth.gov explains that a vaginal culture or a DNA test can also be used to test for the presence of trichomonas.
In Men
Trichomonas vaginalis can also affect men. It can be harder to diagnose this parasite in men because it has a hard time growing and multiplying in the male urinary system. As a result, there is no definitive test for trichomonas in men. Instead, men are often treated for trichomoniasis if any of their sexual partners has been diagnosed with the disease. Men may also be treated for this parasite if they have chronic itching or burning of their urinary system despite receiving treatment for chlamydia or gonorrhea.
