Available testing centers
9 testing options are listed for Riverview, MO. The nearest, Mercy, is about 3.6 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.

Mercy in St. Louis tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C on a sliding-scale fee that applies to everyone, with insurance and Medicaid also accepted; same-visit treatment is available for bacterial STIs, and appointments are required.
Mercy carries DoxyPEP, doxycycline taken after a potential bacterial STI exposure, as a named, prescribable service rather than something to chase down elsewhere. That means a single appointment can produce both a prescription and the clinical conversation needed to use it correctly.
For anyone without a regular primary-care provider, Mercy's panel is particularly complete: herpes testing and hepatitis A, B, and C testing sit alongside HIV and the standard bacterial infections, so a single visit covers exposures that a stripped-down panel would leave unexamined and unaddressed.

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Riverview, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~36% 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.

Local resources & officials
Data & references
Local context
Old Chain of Rocks Bridge frames the northern edge of Riverview the way Riverview Drive frames its spine, and for residents moving along that corridor every day, the practical question of where and when to get screened for STIs is less about motivation than about logistics. With more than half of households here renting at relatively modest monthly costs, budgets tend to be managed carefully, and a test that carries an unexpected fee can quietly fall off the list. The options listed on this page include both low-cost and sliding-scale formats specifically worth checking against your own situation. The community leans toward larger households and a high share of working adults: meaning evenings and weekday mornings fill up fast, and a significant portion of the population is somewhere between their late teens and early thirties, the years when STI exposure is statistically most common and routine screening does the most preventive work.
Unemployment here runs meaningfully higher than state norms, which means schedule unpredictability cuts both ways. Some people have more flexibility mid-week, others are stringing together part-time hours with no guaranteed day off. Several of the clinics listed here offer same-day or walk-in availability, which aligns directly with that kind of irregular schedule.
Getting there
Riverview scores 11.84/20 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.
