Chlamydia trachomatis nucleic acid detection by probe-based assay (urine)

Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like unusual discharge, pain during urination, or if you’ve been exposed to Chlamydia. It’s also part of routine screening for sexually active individuals, especially those with multiple partners or new partners. This test helps catch infections early when treatment is most effective.

What to Expect Before the Test

You’ll likely collect a midstream urine sample at a clinic or lab. No special preparation is needed, but avoid urinating for about an hour before testing to ensure the sample is representative. If you’re pregnant, discuss any concerns with your provider before the test.

What Happens During the Test

The test involves a quick urine sample that’s analyzed in a lab using a specialized probe-based method to detect genetic material from Chlamydia. Results are usually available within 24 to 48 hours, depending on lab processing times.

What the Results Mean

A positive result means Chlamydia bacteria are present in your urine and may require treatment with antibiotics. A negative result means no detectable Chlamydia was found in this sample, but you may still need further testing if symptoms persist or you’ve been exposed recently.
