Mercy-GoHealth Urgent Care in Saint Louis takes walk-ins for STI testing: no appointment needed to get gonorrhea, chlamydia, herpes, hepatitis A, B, and C, or TB screened, with bacterial infections treated the same visit and fees billed to insurance or Medicaid.
Many urgent-care sites route non-English speakers through workarounds that keep them at arm's length from the clinician actually managing their care. At Mercy-GoHealth in Saint Louis, interpretation services are part of the visit itself, so the conversation about symptoms, test results, and treatment happens directly, in full.
Anyone without a regular provider, or paying out of pocket and wanting answers in one stop, benefits from Mercy-GoHealth's broader screening capability: herpes and all three hepatitis strains sit alongside gonorrhea and chlamydia on the same visit, so one walk-in covers ground that usually takes multiple appointments elsewhere.

Mercyin Saint Louis pairs rapid and conventional HIV testing with same-visit treatment for bacterial STIs (gonorrhea, chlamydia, syphilis) all on a fee-based sliding scale that adjusts to income. Medicare and insurance are accepted, and appointments are required.
Plenty of clinics test for gonorrhea, chlamydia, syphilis, and HIV and stop there. Mercy's panel reaches further (herpes, hepatitis A, B, and C, and TB are all on the table) so a single appointment can account for infections that often go undetected simply because they weren't ordered.
Getting a hepatitis C diagnosis at one clinic and chasing treatment elsewhere is the norm for many patients, Mercybreaks that pattern. On-site hepatitis C treatment means the care path stays in one place, and the same is true for hepatitis A and B, which are also managed and vaccinated against at Mercy.
Mercyprescribes PrEP, PEP, and DoxyPEP, which means a patient's prevention strategy (whether ongoing HIV prophylaxis, post-exposure HIV coverage, or post-exposure bacterial STI protection) can be established, adjusted, and monitored without leaving the practice.

Family Care Health Centers in Saint Louis tests for gonorrhea, chlamydia, syphilis, herpes, and HIV, and treats bacterial infections the same visit. Fees follow a sliding scale accepted alongside Medicaid, Medicare, and private insurance. Appointments are required; care is available in Spanish and Vietnamese.
Without a clinician who speaks your language, a diagnosis lands in a gap. Instructions misread, follow-up missed, a prescription not filled correctly. Family Care Health Centers delivers STI care, counseling, and treatment directly in Spanish and Vietnamese, so nothing clinical depends on a second conversation to clarify the first.
When a young person can't seek care without a parent finding out, the visit often doesn't happen, and an untreated infection or unmet contraceptive need compounds from there. Family Care Health Centers operates under Title X, which means minors can access family planning services, including STI-related care, with legal confidentiality protecting that record.
Family Care Health Centers prescribes and manages both PrEP, daily oral medication that blocks HIV acquisition, and PEP, the post-exposure course, without routing those prescriptions through a separate provider. Both regimens require ongoing HIV and kidney-function monitoring, which the clinic handles directly.

Novus Health in Saint Louis takes walk-ins for the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, herpes, rapid and conventional HIV, and hepatitis A, B, and C) with same-visit treatment for bacterial infections, sliding-scale fees, and every test free.
Free HIV and STI testing at Novus Health extends to the full scope of care: TB testing and treatment, hepatitis treatment, PrEP, and HIV medical management all carry no fee. The zero-cost structure applies to the clinical services themselves, not just the initial screening.
Many prevention-focused clinics stock condoms and education but hand off prevention medication to primary care. Novus Health prescribes and manages both PrEP and PEP in-house, including for uninsured patients, so ongoing prevention stays with the same clinical team.
Hepatitis C care at Novus Health runs through direct-acting antivirals prescribed and monitored on-site: the same clinical staff handling diagnosis also oversees the treatment course, meaning viral load follow-up and prescription management stay within one practice rather than splitting across referral networks.

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Mehlville, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% 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
Jefferson Barracks National Cemetery anchors Mehlville's southern edge with the kind of permanence that fits a community where nearly two-thirds of residents own their homes, many of them long-settled families in subdivisions running back from Lemay Ferry Road toward Oakville and Affton. That stability shapes the neighborhood's character, but it doesn't simplify getting tested: the options listed on this page serve the broader St. Louis County corridor, meaning residents typically drive rather than walk to reach a clinic, and fitting an appointment around a working week takes real planning when most households have at least one person clocking in somewhere.
That matters because a meaningful share of Mehlville residents are young adults in their late teens and twenties, the years when STI rates run highest, and those are often the same people balancing odd shifts, shared housing, and competing costs. A household renting near Concord at the typical local rate still has real monthly overhead, and even a modest lab fee lands differently when six-figure incomes represent fewer than one in four households here. With nearly half of adults married and average households running close to three people, a single undetected infection has a short path to a partner.
For residents without coverage or with high-deductible plans, the sliding-scale and no-cost options among the twelve listed here are worth comparing before booking, since out-of-pocket costs vary considerably across the sites and even a short drive down South Lindbergh Boulevard lands you at a different price point.
Getting there

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
