Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like unusual discharge, pain during urination, or if you’re at higher risk for Chlamydia due to sexual history or other factors. It’s also used as part of routine screening for sexually active individuals.

How the Test Works

A small urine sample is collected and analyzed using a probe that targets Chlamydia’s genetic material. This method is highly sensitive and can detect even small amounts of the bacteria.

What to Expect Before the Test

No special preparation is needed. You may urinate into a clean container or use a urine collection device provided by your healthcare team. Avoid urinating right before the test if instructed.

What to Expect During the Test

The test is quick and painless. You’ll likely receive results within hours or a few days, depending on lab processing times.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Chlamydia is a common bacterial infection spread through sexual contact. Left untreated, it can cause pelvic inflammatory disease, infertility, or complications in pregnancy. Early detection and treatment with antibiotics can prevent these issues.
