Chlamydia is caused by a bacteria that most commonly infects the cervix in women and the urethra in men. While infections can also occur in the rectum, throat, and eyes, the Healthyr STD panel only detects infections in the vagina and penis. The bacteria is most commonly spread through vaginal, anal, and oral sex. While most people with chlamydia do not experience symptoms, in women the infection may cause discharge from the cervix, cervical bleeding, painful urination or sex, tenderness in the cervix, or increased frequency of urination. In men chlamydia can cause discharge from the penis, painful urination, or tenderness, pain, or swelling of the testicles. The Healthyr chlamydia test looks for genetic material from the bacteria in your urine, indicating an active infection.
