Chlamydia is a sexually transmitted disease that can affect both men and women. Many people who are infected with the Chlamydia bacteria do not have symptoms but can still transmit it. Chlamydia can affect the urethra (the urine passage), cervix (the neck of the womb), rectum, anus, throat, and eyes. Gonorrhea can cause infections in the genitals, rectum, and throat. It is a very common infection, especially among young people ages 15-24 years.

Syphilis is a bacterial infection usually spread by sexual contact. The disease starts as a painless sore — typically on your genitals, rectum or mouth. Syphilis spreads from person to person via skin or mucous membrane contact with these sores.

A urine test is used to check for protein or blood in your urine, as well as to check for any signs of infection. Protein in your urine may mean that your kidneys are not filtering your blood well enough, and blood in the urine can be a sign of kidney disease.
