St. Louis County reports about 15 new HIV diagnoses per 100,000 residents, near the US average. If you've had a recent risk or simply test on a regular schedule in Hazelwood, Missouri, consider whether you prefer the personalized care of a clinic visit or the convenience and flexibility of an at-home test kit.
Available testing centers
12 testing options are listed for Hazelwood, MO. The nearest, Mercy, is about 1.0 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.
Source: CMS FQHC & Rural Health Clinic enrollment files (data.cms.gov), refreshed quarterly. Title X status reflects the latest OPA grantee list.
Mercy in Hazelwood runs on scheduled appointments, so a confirmed slot means the full panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, plus TB) is ready for you; bacterial infections are treated the same visit, and fees follow a sliding scale open to everyone. DoxyPEP is available for ongoing prevention.
Mercy prescribes doxycycline post-exposure prophylaxis directly, no separate referral to a prescriber. DoxyPEP, taken within 72 hours of a sexual exposure, has shown meaningful reductions in bacterial STI acquisition, and having the prescription originate at the same clinic handling your testing keeps monitoring and follow-up in one place.
For anyone without a primary care provider to order ancillary labs, Mercy's panel extends well past gonorrhea, chlamydia, syphilis, and HIV: herpes and all three hepatitis strains (A, B, and C) are tested here. That breadth is especially useful when cash or insurance constraints make a separate specialist visit impractical.

OSF HealthCare in Bridgeton charges a fee and accepts insurance for a panel covering rapid HIV, syphilis, gonorrhea, chlamydia, hepatitis B, hepatitis C, and TB. With same-visit treatment for bacterial STIs and appointments required.
OSF HealthCare prescribes and manages both PrEP, the daily antiretroviral regimen requiring regular HIV and kidney-function monitoring, and PEP, the post-exposure course. Both protocols stay within the clinic rather than being handed off, meaning the prescribing provider also tracks adherence and orders the follow-up labs the regimens require.
For anyone without a specialist or managing costs out of pocket, OSF HealthCare in Bridgeton provides hepatitis C treatment on-site. Not a test result and a next step elsewhere. The same clinic that runs the antibody test also manages the antiviral treatment, keeping the entire care sequence in one place.
Leaving hepatitis B or C undetected because the panel stopped at the core four means a separate appointment, separate billing, and a window where active infection goes unmanaged. OSF HealthCare's panel includes both hepatitis B and C alongside HIV, syphilis, gonorrhea, chlamydia, and TB, so a single visit surfaces infections that a narrower panel would have missed entirely.

Williams and Associates tests for herpes and hepatitis C alongside gonorrhea, chlamydia, syphilis, and HIV.

Mercy-GoHealth Urgent Care in Florissant tests for gonorrhea, chlamydia, herpes, hepatitis A, B, and C on a sliding-scale fee, with insurance and Medicaid accepted. Walk-ins are welcome, and bacterial STIs are treated the same visit.
Leaving gonorrhea and chlamydia untreated is a known risk, but herpes or hepatitis B can quietly persist when no one orders those tests. Mercy-GoHealth Urgent Care in Florissant runs the full panel: gonorrhea, chlamydia, herpes, and hepatitis A, B, and C, so gaps that require a second appointment elsewhere don't happen here.
Language access at many urgent-care clinics means a card on the counter and instructions to sort it out later. Mercy-GoHealth Urgent Care in Florissant has interpretation services available for non-English languages, so the conversation about symptoms, test results, and treatment happens during the appointment. Not as a separate exercise after it.

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Hazelwood, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~31% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#5 of 115 Missouri counties for chlamydia, a higher rate than 96% of the state
| Infection | St. Louis County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 635.3 6,271 cases ▲ 27% | 498.6 | 492.2 |
| Gonorrhea | 294.7 2,909 cases ▲ 46% | 201.9 | 179.5 |
| Syphilis (P&S) | 16 158 cases ▼ 26% | 21.5 | 15.8 |
| Syphilis (early) | 10 99 cases ▼ 19% | 12.4 | 16 |
| Syphilis (late/unknown) | 30 296 cases ▼ 11% | 33.8 | 29.5 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in St. Louis County, chlamydia has risen from 603.8 to 635.3 per 100,000 (5%), gonorrhea has fallen from 339.5 to 294.7 per 100,000 (13%), and P&S syphilis has risen from 15.5 to 16 per 100,000 (3%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in St. Louis County.
Local HIV snapshot
Federal priority area: Missouri is one of the U.S. jurisdictions prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
St. Louis County HIV care continuum (2023)
St. Louis County recorded 14.7 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. Among St. Louis County residents living with HIV, 75.9% are in care · 65.4% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for St. Louis County tests for syphilis.

Data & references
Local context
Old Town Florissant carries the quiet rhythm of a neighborhood where most households own their homes outright, yards kept up along streets that feed onto Howdershell Road and out toward the wider St. Louis County grid. That stability shapes the community in real ways, but it also masks a practical tension: with nearly four in ten households renting at a monthly figure well below regional norms, a meaningful share of residents are budgeting carefully, and a lab fee or an afternoon off work can genuinely tip the calculation on whether to schedule a test at all. That calculation lands hardest on younger adults in their late teens and twenties, a group Hazelwood has in real numbers. These are people forming new relationships, often mid-career-start, sometimes in households where two or three people share costs and schedules.
With unemployment running above the national floor and fewer than one in five households reaching six-figure income, discretionary time and money are both in shorter supply than the zip code's homeownership rate might suggest. Options with low upfront cost and evening or weekend hours remove the two most common reasons people delay. Getting to a clinic in and around Hazelwood typically means a drive, often a quick run up I-270 or along McDonnell Boulevard. Howdershell Park sits central enough to the neighborhood that residents nearby already know the roads out.
Getting there
Hazelwood scores 10.9/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

Two things that actually depend on Missouri law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In Missouri, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Missouri permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
