Medicaid is accepted, the full panel runs on a sliding scale, same-visit treatment is available for bacterial infections, and an appointment is required.
The no-fee structure at Woman to Woman Health Center applies across the entire visit: testing, treatment, and counseling are all staffed and billed at zero cost to the patient. Medicaid is accepted where applicable, and sliding-scale pricing covers those without coverage, so the operational model is designed to absorb cost at every point of care.
Spanish is a working language at Woman to Woman Health Center, not a routed service, and interpretation is available for languages beyond Spanish. That means clinical communication, from test explanation to treatment instruction, can happen directly and accurately for a wider range of patients.
Beyond the standard four, Woman to Woman Health Center tests for herpes and hepatitis C. Conditions that require specific assays not bundled into a basic panel. Hepatitis C is tested and managed on-site, and herpes testing adds serological detection that would otherwise require a separate referral.

STD stats & rates
How reported STI rates in Ellis County, the county that includes Red Oak, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#98 of 254 Texas counties for chlamydia, a higher rate than 61% of the state
| Infection | Ellis County | Texas | United States |
|---|---|---|---|
| Chlamydia | 357.7 797 cases ▼ 27% | 491.9 | 492.2 |
| Gonorrhea | 111.3 248 cases ▼ 37% | 176.4 | 179.5 |
| Syphilis (P&S) | 6.3 14 cases ▼ 58% | 15 | 15.8 |
| Syphilis (early) | 11.2 25 cases ▼ 58% | 26.4 | 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 Ellis County, chlamydia has risen from 333.6 to 357.7 per 100,000 (7%), gonorrhea has fallen from 126.8 to 111.3 per 100,000 (12%), and P&S syphilis has risen from 5.7 to 6.3 per 100,000 (11%).

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 Ellis County.
Local HIV snapshot
Ellis County HIV care continuum (2023)
Ellis County recorded 12.6 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Ellis County residents living with HIV, 87% are in care · 71.2% 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 Ellis County tests for syphilis.

Local resources & officials
Data & references
Local context
Moving into a unit along The Oaks Boulevard often marks the first stretch of adulthood where health insurance, a regular doctor, and the time to use either all come apart at once. That access gap matters because a meaningful slice of Red Oak's population is at exactly the life stage when transmission risk is highest: people in their late teens and twenties forming new partnerships, sometimes without consistent primary care or insurance. The testing options listed on this page exist in part to address what TX 342 makes plain: getting anywhere in Red Oak means getting in a car, so clinics with flexible hours or low out-of-pocket costs reduce the number of trips a person has to plan around a workday that already claims most of their waking hours.
With nearly three-quarters of residents in the labor force, the households here run on tight schedules. Screening that fits between a shift and school pickup, rather than requiring a separate commute and a waiting room, is what Cherry Creek Nature Preserve afternoons never quite allow.
Getting there
At 6.41/20 on the EPA walkability index, day-to-day errands in Red Oak generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Texas 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 Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Texas 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.
