How we chose these 5 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 5 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.

There were 54 new HIV diagnoses in Merced County in 2023. HIV is the one infection where how soon you test changes which test you need — an RNA test detects it far earlier than a standard antibody test.
Merced County reported 1,454 chlamydia cases in 2023, a rate of 498.1 per 100,000 residents. That is above the national average, which is why routine testing matters here more than it does in most of the country — and most people who have chlamydia or gonorrhea have no symptoms at all, so waiting for something to feel wrong is not a strategy.
HIV prevention & treatment
PrEP, DoxyPEP & Online Treatment
A test result is the start, not the end. If you are negative and want to stay that way, PrEP and DoxyPEP cut the risk of a future infection. If you are positive, most STIs can be treated without setting foot in a clinic. Both are available to people in Merced by video visit, prescribed by clinicians licensed in California.
