How Missouri's program works
Unlike the 5 CDC screening programs elsewhere on this site, there is no single federal program that pays for STD testing nationwide, so Missouri does not have one phone number or one program name to call. Free and low-cost testing instead runs through three separate channels.
Community health centers. Every HRSA-funded Federally Qualified Health Center (FQHC) in Missouri is required by federal law (42 USC 254b) to serve patients regardless of ability to pay, with fees reduced on a sliding scale for uninsured and low-income patients. Most FQHCs offer confidential STI and HIV testing as part of routine primary care. See our directory of FQHCs in Missouri at /clinics/mo/.
State and local health department clinics. Missouri's state and county health departments run their own STD clinics, usually free or low-cost and confidential; many accept walk-ins. Contact your county health department directly, since hours and walk-in policy vary by location.
CDC GetTested. The CDC's own locator at gettested.cdc.gov finds HIV, STD, and hepatitis testing sites in Missouri by ZIP code, and flags which sites offer free or low-cost testing.
All three routes are confidential: results are not shared with an employer, and in most cases not with family, without your consent. None of them requires a specific symptom or reason before you can ask for a test. Chlamydia and gonorrhea in particular often cause no symptoms at all, which is why routine testing, not waiting until something feels wrong, is how most infections actually get caught.
If you qualify for Medicaid, Missouri Medicaid covers STI testing and treatment as a standard preventive benefit. See our Medicaid navigator at /medicaid/missouri/.
For Black families in Missouri
Most community health centers offer confidential STD and HIV testing on a sliding scale, and access matters most where the burden is highest: Black Americans account for roughly a third of chlamydia, gonorrhea, and syphilis diagnoses nationwide despite being 12.6% of the population (CDC, Sexually Transmitted Infections Surveillance, 2023).
For Black residents of Missouri, testing that is confidential, free, and does not require insurance removes two of the biggest barriers to getting tested. Community health centers and the state health department both offer STI testing without an appointment at many locations; the CDC's GetTested locator lists every option in Missouri by ZIP code so you can compare hours and cost before you go.
