Diagnosis of Trichomoniasis

To tell if you have trichomoniasis, your health care provider will do a pelvic exam and lab test. A pelvic exam can show small red sores (ulcerations) on the wall of the vagina or on the cervix (opening to the uterus, or womb). Fluid samples are taken from the vagina in a woman and from the urethra in a man. The infection is harder to find in a man than in a woman.
