You can test for chlamydia at home using a self-collection kit that requires either a vaginal swab or a urine sample, depending on the product and your anatomy. Most kits cost around $99, and in 2025 the FDA authorized the first true at-home chlamydia test that gives you results without mailing anything to a lab. Here’s what you need to know about your options, how to collect a reliable sample, and what to do with your results.
Two Types of Home Tests
Home chlamydia testing falls into two categories, and the difference matters.
Mail-in collection kits are the most widely available option. You collect a sample at home, seal it in the provided packaging, and ship it to a laboratory for analysis. Results typically come back online within a few days. These kits use the same lab technology (called nucleic acid amplification testing, or NAAT) that clinics use, which is sensitive enough to detect the infection from a single copy of the bacteria’s DNA. Companies like Everlywell, myLAB Box, and the CVS-branded kit all follow this model and generally cost around $99. More comprehensive kits that screen for additional STIs can run over $200.
The Visby Medical Women’s Sexual Health Test is the first FDA-authorized test you can buy without a prescription and run entirely at home, no mailing required. It uses a self-collected vaginal swab and a small powered device that connects to a phone app to display results. In clinical testing, it correctly identified 97.2% of positive chlamydia samples and 98.8% of negative ones. It also screens for gonorrhea and trichomoniasis in the same test. The tradeoff: it’s currently designed only for vaginal swab collection, so it’s only an option for people with vaginas.
Most home STI tests are not covered by insurance. If you have a health savings account (HSA), you may be able to use those funds for a pharmacy-purchased kit.
Vaginal Swab vs. Urine Sample
Which sample type you use depends on what the kit provides and your anatomy. Both are highly accurate when done correctly.
Vaginal swabs are the preferred method for people with vaginas. Self-collected vaginal swabs are equivalent in sensitivity and specificity to those collected by a clinician, according to CDC laboratory guidelines. You insert the swab about 5 to 7 centimeters (roughly 2 to 3 inches) into the vagina and gently twist it for 15 seconds. That’s it. Some kits also include a rectal swab, which goes about 2 to 3 centimeters in and is twisted gently against one side for 15 seconds.
Urine samples are the standard for people with penises and are also included in many unisex kits. The key detail here is that you need to collect “first-catch” urine, meaning the very first part of your urine stream, not a midstream sample. You also need to avoid urinating for at least one to two hours before the test. MedlinePlus recommends a two-hour hold; some NHS kits specify one hour. Either way, if you urinate right before collecting, you may wash away the bacteria the test is looking for, which can cause a false negative.
How to Get an Accurate Result
The technology behind these tests is extremely sensitive, but the quality of your sample still matters. A few practical steps reduce your chances of an invalid or misleading result:
- Don’t urinate beforehand. For urine-based kits, hold your urine for one to two hours before collecting. This is the single most common source of user error.
- Collect only the initial stream. Fill the container with the first urine that comes out, not what follows. The initial flow carries the highest concentration of bacteria from the urethra.
- Follow the fill line exactly. Different kits have different volume requirements. Some use a pipette to transfer urine into a tube up to a specific line; others ask you to fill a tube three-quarters full. Too little or too much sample can affect processing.
- For swabs, reach the correct depth. A vaginal swab that only touches the opening may not collect enough cells. Insert it the full 5 to 7 centimeters the instructions specify.
- Ship mail-in kits promptly. Samples degrade over time. Most kits include prepaid overnight or expedited shipping for a reason.
When to Test After Exposure
Timing your test correctly is critical. Chlamydia doesn’t become detectable the moment you’re exposed. There’s limited hard data on exactly when NAAT testing turns positive after a new infection, but clinical guidelines converge on a practical recommendation: wait at least two to three weeks after the sexual contact you’re concerned about.
The British Association for Sexual Health and HIV suggests clinicians wait at least 3 to 7 days before testing for bacterial STIs, while the UK’s National Chlamydia Screening Programme recommends testing at three weeks post-exposure. Some guidelines suggest testing immediately if you’re already at a clinic, then retesting at 3 to 5 weeks to catch anything the first test missed. If you’re ordering a home kit specifically because of a recent encounter, the safest approach is to test at around three weeks after exposure.
Who Should Test Regularly
Chlamydia is often completely silent. Most people who have it don’t know it, which is why routine screening matters more than waiting for symptoms. General guidelines recommend annual testing for sexually active women under 25 and for women 25 and older who have a new partner, multiple partners, or a partner who has other sexual partners or a known STI.
Sexually active gay and bisexual men should test at least annually, and every 3 to 6 months if they have multiple partners or anonymous sexual encounters. For heterosexual men without symptoms and at low risk, routine testing isn’t typically recommended unless they have HIV.
What to Do With a Positive Result
Chlamydia is curable with antibiotics, but you’ll need a prescription. A positive home test result is not a formal diagnosis in the way a clinic result is, but it’s highly reliable given the sensitivity of NAAT technology, and most healthcare providers will treat based on it.
Your options for getting treated include your regular doctor, an urgent care clinic, a local health department STI clinic, a family planning clinic, or a student health center. Many of these offer low-cost or free services. The CDC’s GetTested tool can help you find a nearby location that provides treatment. Some telehealth services affiliated with home test companies can also call in a prescription after reviewing your results.
You should notify any recent sexual partners so they can get tested and treated too. Even after both you and your partner have completed treatment, the CDC recommends retesting in three months to make sure the infection hasn’t returned. This is straightforward to do with another home kit if you prefer not to visit a clinic again.
