CommuniCare Health Centers in Kyle tests for gonorrhea, chlamydia, syphilis, HIV, herpes, and hepatitis, treating bacterial infections the same visit. Fees run on a sliding scale accepted by Medicaid, Medicare, and private insurance. An appointment is required.
Many clinics handling STI care in English-dominant offices rely on workarounds when a patient needs to explain symptoms or ask about a diagnosis in Spanish. CommuniCare Health Centers in Kyle delivers that conversation directly, interpretation services and Spanish-language care are built into the clinical encounter, not layered on after the fact.
For anyone without a regular provider, paying cash or navigating gaps in ongoing care, having herpes and hepatitis A, B, and C testing available at the same appointment as the standard bacterial and HIV workup means fewer clinics to coordinate and a more complete picture in a single visit at CommuniCare Health Centers in Kyle.

Carbon Health in Kyle accepts walk-ins and covers gonorrhea, chlamydia, syphilis, conventional HIV, hepatitis A, hepatitis C, and TB testing in a single visit, with same-visit treatment for bacterial STIs, PrEP, PEP, DoxyPEP, and fees billed to insurance or charged on a standard fee basis.
Carbon Health tests for hepatitis A and hepatitis C in addition to gonorrhea, chlamydia, syphilis, and HIV. Seven pathogens at one visit. Catching hepatitis A or C exposure early changes the clinical path: it opens the door to active monitoring and management rather than an incidental discovery months later.
Leaving Carbon Health in Kyle without a prevention plan (because PrEP, PEP, or DoxyPEP required a separate specialist visit) is a gap this clinic is built to close. All three medications are available on-site, so the decision and the prescription happen at the same appointment.
Carbon Health offers interpretation services for non-English languages, which means every part of the visit (symptom history, treatment instructions, medication guidance) reaches patients in the language they use to make health decisions. That access shapes what care actually gets delivered.

STD stats & rates
How reported STI rates in Caldwell County, the county that includes Lockhart, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~30% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#54 of 254 Texas counties for chlamydia, a higher rate than 79% of the state
| Infection | Caldwell County | Texas | United States |

| Chlamydia | 449.3 224 cases ▼ 9% | 491.9 | 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 Caldwell County, chlamydia has risen from 374.9 to 449.3 per 100,000 (20%), gonorrhea has fallen from 111.2 to 110.3 per 100,000 (1%), and P&S syphilis has risen from 4.4 to 8 per 100,000 (82%).

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 Caldwell County.
Local HIV snapshot
Caldwell County HIV care continuum (2023)
Caldwell County recorded 12 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Caldwell County residents living with HIV, 81.4% are in care · 76.5% 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 Caldwell County tests for syphilis.

Data & references
Local context
South Colorado Street stretches past feed stores and barbecue joints before it bends toward the courthouse square, and from most addresses in town, a clinic run means getting in a car, since nothing here is a short walk away. That drive is real but short, and with the testing options listed on this page, the trip is rarely long. What shapes Lockhart's health landscape is how people actually live here: households run large, with more than three people on average, and nearly four in ten residents rent at around a thousand dollars a month. A budget line that doesn't leave much margin for an unexpected medical bill. For younger adults in their late teens and twenties, who represent a substantial share of the population and face the steepest STI risk simply by stage of life, cost and scheduling can be the whole story.
A clinic that charges on a sliding scale, or offers evening hours, removes the calculation entirely. At the same time, more than half of Lockhart adults are in the workforce, and unemployment is low. Meaning most people here are busy on a fixed schedule, not drifting. Screening that fits between a morning shift and school pickup, somewhere along West San Antonio Street or back down US 183, is screening that actually reaches people where their day already takes them.
Getting there
At 6.55/20 on the EPA walkability index, day-to-day errands in Lockhart 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.
