Mercyin Saint Louis pairs same-visit treatment for bacterial STIs like chlamydia and gonorrhea with a panel that extends to herpes, hepatitis A, B, and C, and TB: all on a fee-based, insurance- and Medicare-accepted sliding scale. Appointments are required.
Mercycarries PrEP and PEP as standing clinical services, meaning someone without a primary care physician, or one whose doctor doesn't prescribe HIV prevention medication, can access both here. No separate referral chain is needed to get the prescription initiated or maintained.
When a hepatitis C test comes back reactive at Mercy, treatment begins at the same location, which means the path from diagnosis to a prescription doesn't cross into a separate specialty practice or require scheduling at a different facility.
Mercy's clinical staff runs herpes and hepatitis A, B, and C testing alongside syphilis, gonorrhea, chlamydia, and HIV. Infections that require either specific physician orders or dedicated lab pathways to include. TB screening is also available, reflecting a panel built for broader infectious-disease coverage rather than the minimum four.

Mercy-GoHealth Urgent Care in Kirkwood takes walk-ins for STI testing across gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB, with bacterial infections treated the same visit; fees are billed to Medicaid or insurance on a sliding scale.
Gonorrhea and chlamydia are the floor, not the ceiling, at Mercy-GoHealth. The panel extends to herpes simplex and all three hepatitis strains (A, B, and C) plus TB, which means a single visit can produce answers across infections rather than requiring separate appointments at separate facilities.
Many urgent-care clinics treat bacterial STIs reactively but won't write a DoxyPEP prescription, the doxycycline-based post-exposure prevention protocol. Mercy-GoHealth Kirkwood does, positioning it as one of the few urgent-care settings where that specific prevention tool is available without routing elsewhere.
Interpretation at Mercy-GoHealth Kirkwood is an operational service built into care delivery: non-English-speaking patients are connected through staffed interpretation rather than an ad hoc workaround, so clinical conversations about testing, treatment, and prevention carry the same precision regardless of which language they happen in.

SLUCare in Saint Louis requires an appointment, so scheduling ahead is the entry point to a visit that covers gonorrhea, chlamydia, syphilis, HIV, hepatitis B and C, herpes, and TB: with same-visit treatment for bacterial infections, sliding-scale fees, and insurance accepted.
Without a clinic that handles prevention prescriptions directly, a gap between exposure and a first PrEP dose, or between need and PEP access, falls to the patient to close across multiple providers. SLUCare manages both PrEP and PEP in Saint Louis, keeping that gap inside a single care relationship rather than a to-do list.
SLUCare tests for herpes and both hepatitis B and C alongside the standard bacterial and viral panel, which means conditions that would otherwise require a separate visit get documented and addressed in the same appointment.

SSM Health Saint Marys Hospital in St. Louis runs STI care with appointments, testing for gonorrhea, chlamydia, syphilis, herpes, rapid and conventional HIV, hepatitis A, B, and C, and TB. Bacterial infections treated the same visit. Fees are charged on a sliding scale, with insurance and Medicaid accepted.
For someone managing an ongoing condition like HIV or hepatitis C, where medication adherence counseling is part of every visit, SSM Health Saint Marys Hospital in St. Louis has French- and Spanish-speaking staff and broader interpretation services, so that nuanced conversation about dosing, side effects, and follow-up happens without a layer of translation between the patient and the clinician.
SSM Health Saint Marys Hospital in St. Louis prescribes both PrEP and PEP through its own providers, which means the baseline lab work, ongoing kidney and HIV monitoring required to safely maintain PrEP, and the follow-up visits that keep both medications effective are all handled within the same clinical system. Not handed off.
Without on-site hepatitis C treatment, a positive antibody result typically means a second appointment with a separate specialist. A gap where patients fall out of care entirely. SSM Health Saint Marys Hospital in St. Louis moves directly from diagnosis to treatment, so the viral load confirmation and the prescription for antivirals happen within the same system that ran the test.

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Frontenac, 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
South Lindbergh Boulevard cuts through one of St. Louis County's most settled communities, where nearly every household owns its home and a strong majority of adults are married. That stability shapes the rhythm of daily life in Frontenac, but it doesn't erase the reality that a meaningful share of residents are young adults navigating early relationships, new partners, or the years when routine sexual health screening matters most and is easiest to defer. Two details about this community are worth holding together: with unemployment barely registering and labor-force participation running below two-thirds, many residents are either intensely busy in demanding careers or outside the workforce entirely: retired, caregiving, or otherwise. Neither profile puts STI screening naturally on the calendar.
Add the fact that three in four households here are high earners, which means cost is rarely the obstacle, but schedule and social habit often are. Younger adults in Frontenac who want to be tested are less likely to be brushing up against financial barriers than against the quiet assumption that this is someone else's concern. Frontenac's above-average scores mean that reaching the options listed on this page, several in and around neighboring Creve Coeur and Kirkwood, doesn't require clearing an afternoon. A short drive, or in some cases a direct walk along North Lindbergh Boulevard, keeps screening from becoming an expedition.
Getting there
At 9.18/20 on the EPA walkability index, day-to-day errands in Frontenac generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
