Recently, tests that are much more accurate have become available, including DNA tests that are reliable in males and females. These tests can be done with vaginal swabs or urine. One of these tests even allows healthcare providers to check for trichomoniasis, chlamydia, and gonorrhea using the same sample.
Tests for Trich
A culture test is another test for trich and can be used with males and females. Culture tests use urine or a swab from the vagina or urethra, and make the trich parasite easier to find by “growing” it in a lab.
Sometimes healthcare providers will put a sample of vaginal fluid or discharge on a slide so they can see the parasite under a microscope (this is called a “wet prep”). This test is not always reliable.
