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 that the laboratory found signs of the infection in your sample. Try not to worry, because many of these infections are easy to treat with a short course of medication. Our medical team will reach out to discuss your result, arrange treatment if needed, and advise you on how to talk with your partner about getting tested.
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.
It is best to avoid sex until your results are back and any treatment is fully completed. If you do have sex in the meantime, using a condom every time can lower the risk of passing an infection to your partner. Once your results arrive, share them with your partner so they can consider testing and treatment as well.
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.
The frequency depends on your risk factors. The CDC recommends annual testing for sexually active women under 25 or those with multiple partners. If you’re at higher risk (e.g., new partners, STI history), testing more often may be advised.
