Symptoms: common does not mean specific
Possible findings include burning urination, genital discharge, bleeding between periods or after sex, pelvic discomfort, testicular pain, or rectal pain/discharge after rectal exposure.

How is it diagnosed?
A validated molecular test, such as PCR, is preferred. The correct sample may be first-catch urine or a vaginal, cervical, rectal or throat swab according to anatomy and exposure site.
