Mercy in Kirkwood runs by appointment, so scheduling ahead is how you get the full visit: rapid and conventional HIV testing, the complete bacterial panel, and same-visit treatment for gonorrhea and chlamydia, all on a sliding scale with Medicaid and Medicare accepted.
Mercy tests for herpes and all three hepatitis strains (A, B, and C) in addition to HIV, syphilis, gonorrhea, and chlamydia. A wider panel at a single appointment means fewer gaps to chase down separately, and a clearer picture of where you actually stand.
Mercy carries DoxyPEP as a standing preventive option: useful for anyone paying cash, without a regular prescriber, or who wants the medication sourced from the same place handling their testing. The prescription happens at the clinic, not through a separate appointment elsewhere.

Summers Healthcare in Saint Louis runs appointment-based STI care with a sliding-scale fee structure open to all, covering the standard bacterial and viral panel with same-visit treatment for bacterial infections, plus HPV vaccination, PrEP, PEP, and DoxyPEP.
Summers Healthcare holds standing capacity to prescribe PrEP, PEP, and DoxyPEP. Making it the right fit for someone paying out of pocket who needs prevention medication managed without hunting down a separate prescriber or navigating a referral chain to access all three.
After a hepatitis C antibody test confirms infection, Summers Healthcare moves directly into treatment. Prescribing direct-acting antivirals and monitoring viral load response in-house, so the clinical relationship that caught the infection is the same one managing the cure.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Summers Healthcare tests for herpes and hepatitis A, B, and C, which means a single visit can surface infections that a narrower screen would have left undetected and unaddressed.

| Gonorrhea | 7 days after exposure | 14 days after exposure |
| Trichomoniasis | 7 days after exposure | 28 days after exposure |

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Crestwood, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~19% 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
Watson Road cuts through the middle of Crestwood's daily life, connecting residents to groceries, schools, and the kind of errands that fill a week without much thought. Most households here are owner-occupied, with families that tend toward the larger end of the suburban average, and the majority of adults are married, which shapes how health decisions get made: conversations happen at home, appointments get coordinated around two schedules, and routine care sometimes waits until it fits both. That household stability coexists with a share of young adults, people in their late teens and twenties forming new relationships, for whom STI screening is simply part of staying well but rarely feels urgent enough to schedule alone. Nearly four in ten Crestwood households bring in six figures, and unemployment sits near the floor, so the obstacle here is rarely cost outright; it is more often the calendar.
St. Louis County carries STI rates that reflect a genuinely dense, interconnected metro region, and Crestwood residents move through that region constantly, along I-44, down Gravois Road, past Laumeier Sculpture Park on weekend afternoons. Staying current with screening is less about alarm than about recognizing that county-level transmission patterns do not stop at municipal lines.
Getting there
Crestwood scores 11.73/20 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.
