How we chose these 10 clinics
- Every one is on the CDC’s GetTested locatorThe wider CDC directory we draw from has over 16,000 entries. Only the ones GetTested also lists can appear here, and all 10 clinics below do.
- Listings that name fewer than three tests are left outEven on GetTested, 527 listings name fewer than three tests. We don’t show them anywhere.
- Unverified pregnancy centers are never shownThe CDC lists some pregnancy centers whose STD testing we couldn’t verify. We don’t list them anywhere.
- Cost is stated the way the CDC lists itFree, sliding scale or insurance accepted, as each clinic reports it to the CDC. We don’t estimate prices, and if the listing says nothing, the card says “Fees not listed.”

Testing privacy
Anonymous vs. confidential testing
Most clinics test confidentially. Some also offer anonymous testing, usually for HIV. Availability varies by testing site, so ask when you call.
Confidential
- You give your name, and the result goes in your medical record.
- Results are not available to the public.
- Chlamydia, gonorrhea, syphilis and HIV are reportable in every state, so a positive result is reported to the health department. Those reports are kept confidential.
Anonymous
- You don’t give your name.
- You receive a number and use it, not your name, to get your result.
- Not every site offers it. Ask before your visit.
