Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like unusual vaginal discharge, pain during urination, or if you’re at higher risk for STIs (e.g., new sexual partners, unprotected sex). It’s also used during routine screenings for sexually active individuals.

How the Test Works

A swab is gently collected from the vagina to check for *Chlamydia trachomatis* bacteria. The sample is then sent to a lab for culture, where bacteria are grown under controlled conditions to confirm infection.

What to Expect Before the Test

No special preparation is needed. You may shower or clean your genital area the day of the test, but avoid using douches, vaginal creams, or tampons to avoid interfering with results.

What to Expect During the Test

The swab is inserted into the vagina briefly, and you may feel mild discomfort or pressure. The procedure takes just a few minutes and doesn’t require anesthesia.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Untreated *Chlamydia* can lead to complications like pelvic inflammatory disease, infertility, or increased risk of HIV transmission. Early diagnosis and treatment with antibiotics can prevent these issues and protect sexual partners.

Frequently asked questions

How long does it take to get results?
Results are typically available in 3 to 10 business days, depending on lab processing times. Follow-up with your provider if you have concerns.
What if the test is positive?
If positive, you’ll need antibiotics (e.g., azithromycin or doxycycline) to clear the infection. Both you and your sexual partners should be treated to prevent reinfection.
Can I have sex while waiting for results?
No, avoid sexual contact until you’ve completed treatment and results confirm clearance of the infection. Always discuss this with your provider.
