Short answer
Free and low-cost STI testing is available in many parts of the United States through public health clinics, local health departments, community health centers, family planning clinics, Title X clinics, HIV service organizations, mobile events, and some pharmacies. The key is to confirm what the site actually offers: HIV only, chlamydia/gonorrhea, syphilis, hepatitis, pregnancy-related testing, treatment, partner services, or body-site swabs.
Where to start
| Option | What it can help with | What to confirm |
|---|---|---|
| CDC GetTested | Searches for HIV, STI, viral hepatitis testing, and vaccines near you. | Whether the location offers the specific STI tests you need and whether appointments are required. |
| HIV.gov services locator | Finds HIV testing and related services, and may include STI testing services. | Whether the site provides HIV only or broader STI testing. |
| Local health department | Often provides confidential testing, treatment, partner services, or referrals. | Cost, walk-in hours, eligibility, and which tests are available that day. |
| Title X family planning clinic | HHS says Title X clinics offer voluntary, confidential services regardless of ability to pay. | Whether STI testing, HIV testing, contraception, or pregnancy-related care is available at that site. |
| Community health center or sexual health clinic | May offer sliding-scale care, testing, treatment, PrEP, vaccines, and follow-up. | Fees, insurance billing, confidentiality, PrEP lab coverage, and follow-up process. |
Use locators, then call or check the clinic page
CDC's GetTested site says that if you are not comfortable talking with your regular health care provider about STIs, many clinics provide confidential and free or low-cost testing. HIV.gov also says HIV tests are available in many settings, including health clinics, health departments, family planning clinics, pharmacies, community organizations, mobile testing events, and at home. Locator results are a starting point, not a guarantee that every test is offered at every location.
Insurance and cost
HIV.gov says HIV screening is generally covered by insurance without a copay under the Affordable Care Act, including most Medicaid programs, and that some sites offer free or low-cost tests for people without insurance. STI costs vary more widely. Ask about visit fees, lab fees, whether treatment is included if a test is positive, and whether using insurance will generate an explanation of benefits sent to the policyholder.
Confidentiality and teens
Confidentiality rules can depend on the type of clinic, state law, age, insurance, and the service being provided. HHS says Title X services are voluntary, confidential, and provided regardless of ability to pay. Teens and people on someone else's insurance should ask directly how privacy, billing, online portals, lab results, and follow-up calls are handled. For EOB and insurance questions, see the STI testing privacy and insurance guide.
Do not assume "full panel" means complete
"Full panel" is not a standardized medical term. A site may test for HIV, syphilis, chlamydia, and gonorrhea, but not herpes, hepatitis, trichomoniasis, HPV/Pap cervical screening, or site-specific throat and rectal infections. If you had oral or anal sex, ask whether throat or rectal swabs are available. For timing and coverage questions, read the HIV window period guide, the chlamydia and gonorrhea testing guide, the hepatitis B and C testing guide, the trichomoniasis testing guide, the HPV testing and Pap tests guide, and the Full STI panel guide.
HPV and Pap screening access
HPV tests and Pap tests are cervical cancer screening tools, not general STI tests. If cost is the barrier, CDC says its National Breast and Cervical Cancer Early Detection Program helps eligible people access free or low-cost cervical cancer screening. Ask whether the site provides Pap testing, HPV testing, follow-up for abnormal results, or referral only.
PrEP labs and cost questions
Some clinics help with HIV PrEP visits, medication access, and lab monitoring. Ask whether the site handles HIV testing, kidney function labs, hepatitis B screening, STI testing, and refills or injection visits. If the concern is a possible HIV exposure in the past 72 hours, ask about urgent PEP access rather than routine scheduling. For condom breaks or recent exposure questions, see the STI testing after condom break or possible exposure guide. For anonymous partner or one-night stand timing, see the anonymous partner testing guide. For testing after sex during a trip, see the STI testing after vacation or travel sex guide. For sexual assault or nonconsensual exposure, see the STI testing after sexual assault guide. For timing differences, see the PrEP vs PEP testing timelines guide. For the PrEP lab checklist, see the PrEP labs and STI testing follow-up guide.
When clinic testing may be better than at-home testing
At-home tests can help with privacy and access, but a clinic may be better if you have symptoms, are pregnant, had a recent exposure, need a physical exam, need treatment right away, need body-site swabs, need sexual assault medical forensic care, or need help with partner notification. For partner services and EPT questions, see the partner notification and EPT guide. See the at-home STI tests versus clinic testing guide for the tradeoffs.
Questions to ask before you go
- Which infections are included, and which are not?
- Do you offer throat, rectal, vaginal, cervical, urethral, urine, or blood testing as needed?
- What will I pay for the visit, the lab, and treatment if anything is positive?
- Can I use the service without insurance, and will anything be billed to my insurance?
- How confidential are results, portals, text messages, phone calls, and billing documents?
- If a result is positive, do you provide treatment, prescriptions, partner services, or referrals?
If you need recurring testing because of open relationships, multiple partners, PrEP, or DoxyPEP, ask whether the clinic can support repeat visits, body-site swabs, and confidential result delivery. See the open relationship and multiple-partner testing guide.
