Frequently asked questions

Can I get tested for STDs without insurance?
Yes. The clinics listed here serve uninsured patients, and most charge on a sliding scale based on your household income, so testing may be free or low-cost depending on what you earn. Each listing shows the clinic's fee structure; call ahead to confirm what testing costs there.
Do these clinics also test for HIV?
Many do. Clinics on this page that list HIV testing among their services are marked "Also tests for HIV". If HIV testing matters to you, confirm it when you call.
Can a teenager get tested without a parent?
In every state and Washington, DC, minors can consent to STI testing and treatment themselves, according to the Guttmacher Institute. Eight states set a minimum age (12 or 14, for example), and some states allow or require a provider to notify parents in certain situations, such as a positive HIV test. Ask the clinic about its confidentiality policy when you call.
What if there's no clinic close enough?
The CDC's GetTested locator (gettested.cdc.gov) lists HIV, STD and hepatitis testing sites across the country, many of them free or low-cost. Your county health department is also worth calling: many run their own STD clinics.
