Why Get Tested?

To screen for or diagnose a chlamydia infection

When to Get Tested?

For screening: may be recommended if you are sexually active, pregnant or considering pregnancy, or at increased risk for this sexually transmitted disease (STD)
For diagnosis: when you have symptoms of this STD, such as such as vaginal discharge and abdominal pain (for women) or unusual discharge from the penis or pain on urination (for men); when a newborn has conjunctivitis

Sample Required?

A swab or brush of cells or secretion from the infected area or a first-catch urine sample

Test Preparation Needed?

Tell your health care provider about use of antibiotics or, for women, douches or vaginal creams within 24 hours before testing vaginal samples, as they may affect test results. You may be instructed to wait one to two hours after you last urinated before collecting a urine sample. Follow any instructions you are given.
