Getting tested for chlamydia is straightforward: you either pee in a cup or have a swab taken, and results typically come back within a day. Most primary care doctors, urgent care clinics, sexual health clinics, and community health centers offer the test, and many provide it for free or at low cost. Here’s what to know before you go.
Who Should Get Tested
The U.S. Preventive Services Task Force recommends annual chlamydia screening for all sexually active women 24 and younger. Women 25 and older should also be screened if they have risk factors like a new sexual partner, more than one partner, inconsistent condom use, a partner who has other partners, a previous STI, or a partner with an STI.
For men, there’s no blanket screening recommendation, but testing is important if you have symptoms, a partner who tested positive, or multiple partners. The CDC specifically recommends that men who have sex with men get tested at all exposed body sites at least annually, regardless of symptoms. Rectal and throat infections often cause no symptoms at all but can still be passed to partners and increase the risk of acquiring HIV.
When to Test After Exposure
Chlamydia won’t show up on a test immediately after exposure. If you think you were exposed, wait at least one week before testing. Two weeks after exposure catches nearly all infections. Testing too early can produce a false negative, meaning you’re infected but the test misses it because the bacteria haven’t multiplied enough to detect.
If you have symptoms like unusual discharge, burning during urination, or pelvic pain, get tested right away. Symptoms typically mean the infection has been present long enough to detect.
How the Test Works
The standard chlamydia test is called a nucleic acid amplification test, which detects the DNA of the bacteria. It’s the most accurate option available. You’ll either provide a urine sample or have a swab collected from the vagina, urethra, rectum, or throat, depending on where you may have been exposed.
A urine test is slightly less accurate than a vaginal or urethral swab, but it’s the most common method because it’s noninvasive. Vaginal swabs can often be self-collected, meaning a clinician hands you the swab and you do it yourself in a private room. Rectal and throat swabs are quick and involve a gentle brush or cotton-tipped swab at the site.
The test itself takes seconds. There’s no blood draw involved for chlamydia specifically, though your provider may offer blood tests for other STIs like HIV or syphilis at the same visit.
Where to Get Tested
You have several options:
- Your regular doctor or gynecologist can order the test during a routine appointment. You can ask for STI screening even if you’re there for something else.
- Sexual health or STI clinics specialize in this kind of testing and often provide confidential, free, or low-cost services. The CDC’s GetTested tool (gettested.cdc.gov) helps you find a clinic near you by ZIP code.
- Planned Parenthood and community health centers offer testing on a sliding-fee scale based on income.
- Urgent care clinics can typically run the test, though availability varies by location.
If cost is a concern, publicly funded clinics often test for free. Most private insurance plans cover STI screening with no copay when it falls within recommended guidelines.
At-Home Test Kits
Mail-in test kits let you collect a sample at home (usually a urine sample or genital swab) and send it to a lab. The lab technology is the same as what clinics use, so the tests themselves are reliable. The weak link is sample collection. If the swab isn’t done correctly or the urine sample is too dilute, you’re more likely to get a false negative.
A false negative means you have the infection but the test says you don’t. A false positive, where the test flags an infection that isn’t there, is also possible but less common. If you use a home kit and get a positive result, you’ll still need to see a provider for treatment, since chlamydia requires a prescription antibiotic.
Getting Your Results
Lab results are usually ready within one day. Some clinics offer rapid tests that return results in 90 minutes or less, though these aren’t available everywhere. Most providers will contact you by phone, patient portal, or secure message. Some clinics only call if the result is positive, so ask upfront how you’ll be notified.
What Happens If You Test Positive
Chlamydia is curable with antibiotics. Your provider will prescribe a course of medication, and the key is finishing the entire prescription exactly as directed, even if symptoms go away before the medication runs out.
You’ll need to tell any recent sexual partners so they can get tested and treated too. This can feel uncomfortable, but it’s essential. Your partner may have the infection without symptoms, and untreated chlamydia can lead to serious complications including infertility. Some health departments offer anonymous partner notification services if you’d rather not deliver the news yourself.
Avoid sex until you and your partner have both completed treatment. Even after successful treatment, get retested three months later. Reinfection is common, particularly if a partner wasn’t treated or if you have a new partner.
