Tests offered
Fees & payment
Center Street Community Clinic in Marion meets patients who are paying out of pocket, between insurance plans, or stretching limited incomes. Exactly the people federal qualification is designed to reach. Sliding-scale fees make syphilis, gonorrhea, and chlamydia screening genuinely affordable, with no appointment required.
Tests offered
Fees & payment
Optum in Delaware tests for HIV, syphilis, gonorrhea, chlamydia, and hepatitis A, B, and C. With same-visit treatment for bacterial infections when you need it. Appointments are required, and fees run on a sliding scale with Medicaid and insurance accepted.
PrEP at Optum means a provider writes the prescription, tracks lab work, and schedules the follow-up visits that keep the regimen current: daily oral PrEP requires regular HIV and kidney-function monitoring, and that cycle runs entirely within the clinic rather than split across separate offices.
Anyone managing care without a regular primary-care provider, or paying out of pocket, benefits from Optum's standing capacity to test for hepatitis A, B, and C alongside the core bacterial and HIV panel, consolidating labs that would otherwise require a separate appointment elsewhere.

STD stats & rates
How reported STI rates in Union County, the county that includes Richwood, compare with Ohio and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#37 of 88 Ohio counties for chlamydia, a higher rate than 58% of the state
| Infection | Union County | Ohio | United States |
|---|---|---|---|
| Chlamydia | 259.9 181 cases ▼ 44% | 461.7 | 492.2 |
| Gonorrhea | 54.6 38 cases ▼ 67% | 168 | 179.5 |

| Syphilis (early) | 5.7 4 cases ▼ 38% | 9.2 | 16 |

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 Union County, chlamydia has risen from 246.9 to 259.9 per 100,000 (5%), gonorrhea has fallen from 89.2 to 54.6 per 100,000 (39%), and P&S syphilis has fallen from 12.7 to 11.5 per 100,000 (9%).

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 Union County.
Local HIV snapshot
Union County HIV care continuum (2022)
Union County recorded 9 new HIV diagnoses per 100,000 (2022), against 8.8 statewide and 13.7 nationally. Among Union County residents living with HIV, 72.8% are in care · 67.9% 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 Union County tests for syphilis.

Data & references
Local context
Richwood's STI picture tracks with Union County's broader rural patterns, elevated enough that routine screening matters, yet the practical path to a clinic isn't a quick errand. That workforce reality shapes everything. With labor-force participation running high and unemployment extremely low, most adults in Richwood are employed and structured around fixed hours. The kind of schedule that turns an afternoon appointment into a logistical puzzle.
Rent hovering around $804 a month also means out-of-pocket costs for uninsured visits register as a real line item, not a rounding error. For younger adults still forming relationships, the under-35 crowd, these compounding constraints are exactly why the options listed on this page matter: the 24 choices are ranked by proximity precisely because distance is the central variable here. Richwood's relatively high homeownership rate and average household size hint at a community where relationships are stable but not necessarily talk-openly-about-testing comfortable. Low-cost and telehealth-assisted options among the listings can sidestep that social awkwardness entirely, and for anyone starting from the highway out of town, knowing which listed clinic sits closest cuts the guesswork before you ever pull out of the driveway.
Getting there
At 4.29/20 on the EPA walkability index, day-to-day errands in Richwood 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 Ohio 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 Ohio, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Ohio 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.
