Available testing centers
7 testing options are listed for Chain of Rocks, MO. The nearest, Mercy, is about 6.0 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 Troy covers gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, TB, and rapid or conventional HIV testing. With same-visit treatment for bacterial infections and fees on a sliding scale. Appointments are required. DoxyPEP is available for ongoing prevention.
DoxyPEP at Mercy involves an actual prescribing relationship: a clinician reviews your history, writes the prescription, and can monitor ongoing use over time. That means the antibiotic regimen is dosed correctly and adjusted if your situation changes, rather than left to guesswork.
A basic four-pathogen panel leaves herpes and all three hepatitis strains undetected, which means a second appointment somewhere else, and a window where treatment hasn't started. Mercy's panel catches all of them in a single visit, so nothing slips through waiting on a separate referral to materialize.

Compass Health Network in Wentzville requires an appointment, and that single visit covers the standard panel (gonorrhea, chlamydia, syphilis, rapid and conventional HIV) plus hepatitis C and TB testing, with fees on a sliding scale and same-visit treatment for bacterial infections.
Beyond the core bacterial and HIV panel, Compass Health Network runs hepatitis C antibody testing and carries on-site treatment, so a reactive result doesn't park a patient in a waiting period while care gets arranged elsewhere. Hepatitis A and B vaccines round out the hepatitis coverage at the same visit.
Compass Health Network offers substance-use treatment alongside STI care, which means a provider addressing an active infection can also engage with a contributing behavioral health need at the same facility. Rather than leaving those two threads unconnected across different systems.

STD stats & rates

#45 of 115 Missouri counties for chlamydia, a higher rate than 61% of the state

|---|---|---|---|
| Chlamydia | 276.7 179 cases ▼ 45% | 498.6 | 492.2 |

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 Lincoln County, chlamydia has risen from 261.9 to 276.7 per 100,000 (6%), gonorrhea has fallen from 134.3 to 51 per 100,000 (62%), and P&S syphilis has fallen from 8.4 to 3.1 per 100,000 (63%).

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 Lincoln 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.
Lincoln County HIV care continuum (2020)
Lincoln County recorded 0 new HIV diagnoses per 100,000 (2020), against 10.6 statewide and 13.7 nationally. Among Lincoln County residents living with HIV, 88.2% are in care · 79.4% 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 Lincoln County tests for syphilis.

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.
