Rated 3.4 out of 5 from 6 reviews

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.

PrEP and PEP Prescribed Without a Separate Referral

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.

Herpes and Hepatitis Testing Included in the Panel

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.

French and Spanish Spoken, Interpretation Beyond That

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.

Hepatitis C Treatment Stays Inside This Clinic

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.

STDs & HIV in St. Louis County: the local picture

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.

Congenital syphilis is the fastest-rising STI: what to test, and when

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

About Clayton, MO

Wydown Skinker sits at the edge of Washington University's Hilltop Campus Historic District, home to a mix of long-term homeowners and renters cycling through on academic and professional contracts. That split matters for STI screening: when more than half of Clayton households own and have planted roots here, and a meaningful share rent on shorter timelines, the population turning over most quickly tends to be younger adults still forming relationships, exactly the people for whom a missed or delayed test carries the most consequence. Clayton's labor picture adds another layer. With just over half the population counted in the workforce and unemployment practically nonexistent, the residents who are working tend to be working hard, which makes clinic hours and location real factors, not incidental ones.

More than half of households here earn above six figures, yet the options listed on this page span a range of fees and appointment types, meaning cost alone shouldn't be the thing that keeps someone from scheduling. Louis County area and vary enough in hours, price point, and appointment style that someone commuting along Forest Park Parkway at odd hours has genuinely different choices than a Hi-Pointe resident with a flexible afternoon. That range is what makes consistent screening realistic for Clayton's particular mix of schedules and living situations.

Confidentiality & consent in Missouri

Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

In Missouri, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.

Can my partner be treated too? (EPT)

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.
