How the Test Works

Your healthcare provider will collect a sample from your vagina using a sterile swab. The swab is then tested in a lab using a specialized probe to identify genetic material from *Chlamydia*. This method is highly sensitive and can detect even small amounts of the bacteria.

What to Expect Before the Test

You may have some mild discomfort or light spotting during the sample collection, but it usually doesn’t require any special preparation. Avoid douching or using vaginal products 24 hours before the test for best accuracy.

What to Expect After the Test

Most people don’t need to do anything special after the test. If you have any unusual symptoms or concerns, contact your healthcare provider. Results are typically available within a few days.

Why This Test Matters

*Chlamydia* is a sexually transmitted infection (STI) that can cause serious health problems if untreated, including pelvic inflammatory disease, infertility, or complications during pregnancy. Early detection helps prevent these issues and allows for prompt treatment.

Frequently asked questions

How long does it take to get results from this test?
Results are usually ready within 2–5 business days. Your provider will discuss the results with you during your follow-up visit.
Can I still have sex while waiting for my results?
It’s best to avoid sexual contact until you’ve received your results and any recommended treatment. This helps prevent spreading the infection to others or reinfecting yourself.
What if I get a positive result?
If your test is positive, your healthcare provider will prescribe antibiotics to treat the infection. You’ll need to finish the full course, even if symptoms disappear. Follow-up testing may be recommended to confirm the infection is cleared.
