Chlamydia trachomatis Nucleic Acid Detection (Urine) – Probe-Based Test
This test checks for the presence of genetic material from *Chlamydia trachomatis*, a common bacterial infection that can affect the genitals, throat, or rectum. It helps identify infections that may cause pain, discharge, or other symptoms.

This test is done to check whether you have a sexually transmitted infection, even if you currently have no symptoms. Many infections do not cause noticeable signs early on, so testing is the only reliable way to know your status. Early detection allows prompt treatment, lowers the risk of complications, and helps protect your partner's health.
Doctors may recommend this test if you have symptoms like unusual discharge, pain during urination, or bleeding, or if you’re at higher risk for chlamydia (e.g., sexually active with multiple partners, recent STI exposure). It’s also part of routine screening for sexually active individuals under certain guidelines.
The test works by detecting traces of the infection in the sample you provide. After you collect your sample at home and send it to our certified laboratory, trained technicians run the analysis, and a qualified medical professional reviews and approves your result before it is released to you through your secure online account.
The test uses a urine sample to detect genetic material from *Chlamydia trachomatis* through a molecular probe. If chlamydia DNA is present, the test can identify it quickly, often within hours.
Collecting your sample is simple and usually takes only a few minutes. Your kit includes everything you need, such as a sterile swab or collection tube, clear step-by-step instructions, and a prepaid return envelope. Follow the instructions carefully, avoid touching the tip of the swab, seal the sample as directed, and mail it back as soon as possible.
You’ll collect a midstream urine sample (a few seconds of urine flow) in a sterile container. No special preparation is needed, but avoid urinating right before the test.
Most results are ready within a few business days after the laboratory receives your sample. You will receive an email or text message as soon as they are available, and you can view them privately in your account at any time. If your result requires follow-up, a member of our medical team will contact you to explain the next steps and answer your questions.
Results are typically ready within 24 hours. A positive result means chlamydia DNA was found, which may indicate an infection. A negative result means no chlamydia DNA was detected at the time of testing.

Frequently asked questions
If you have symptoms or risk factors, a positive test confirms chlamydia infection and guides treatment. Untreated chlamydia can lead to complications like pelvic inflammatory disease, infertility, or increased risk of HIV transmission. Early treatment with antibiotics can clear the infection and prevent long-term harm.
A positive result means the test detected genetic material from *Chlamydia trachomatis*, strongly suggesting an infection. You’ll need to follow your healthcare provider’s advice for treatment, which usually involves antibiotics.
Yes, but use protection (e.g., condoms) to avoid spreading the infection. If you’re sexually active, both you and your partner should be tested and treated if needed.
