Texas Department of State Health Services in Hearne tests for gonorrhea, chlamydia, syphilis, HIV, and hepatitis B and C on a sliding-scale fee accepted by Medicare and most insurers; gonorrhea, chlamydia, and syphilis are treated the same visit, and appointments are required.
DoxyPEP, doxycycline taken after a potential bacterial STI exposure, requires a provider who can assess eligibility, write the prescription, and track outcomes over time. The staff here handle all three: clinical evaluation, the prescription itself, and the follow-up monitoring that makes the regimen effective rather than haphazard.
For anyone without a regular primary care provider, consolidating hepatitis B, hepatitis C, and TB screening with a full bacterial and HIV panel in a single appointment closes gaps that would otherwise require separate referrals across multiple offices. The clinic carries hepatitis B vaccination as well, so screening and protection happen together.

HealthPoint Hearne, serving Hearne residents who are uninsured, paying cash, or caught between providers, earns its federally qualified designation by tying STI screening costs to income. Walk-ins are welcome for syphilis, gonorrhea, and chlamydia testing on a sliding-scale fee schedule.
Tests offered
Fees & payment
HealthPoint in Hearne tests for HIV, syphilis, chlamydia, gonorrhea, herpes, and hepatitis A, B, and C on a sliding-scale fee accepted by Medicaid, Medicare, and most insurers. Appointments are required; bacterial STIs are treated same visit, and care is delivered in Spanish.
When clinical communication has to pass through an intermediary, follow-up questions go unasked, dosing details get compressed, and nuance about symptoms or timelines disappears. At HealthPoint, Spanish-language care is provided directly (the same visit, the same clinician) so nothing between symptom and treatment gets lost in the handoff.
HealthPoint prescribes and manages PrEP: meaning the required HIV baseline test, the follow-up labs at 90-day intervals, and the prescription itself are handled within the clinic rather than split across separate providers. PEP is also available, filling out the prevention side for situations where ongoing daily medication isn't the right fit.
For someone without a regular primary care provider, or paying cash and trying to consolidate labs into a single visit, HealthPoint's panel covers herpes and hepatitis A, B, and C in addition to gonorrhea, chlamydia, syphilis, and HIV. That range matters when a single appointment needs to answer more than one clinical question.

STD stats & rates
How reported STI rates in Robertson County, the county that includes Calvert, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#33 of 254 Texas counties for chlamydia, a higher rate than 87% of the state
| Infection | Robertson County | Texas | United States |
|---|---|---|---|
| Chlamydia | 544.4 94 cases ▲ 11% | 491.9 | 492.2 |
| Gonorrhea | 179.5 31 cases ▲ 2% | 176.4 | 179.5 |
| Syphilis (P&S) | — no data | 15 | 15.8 |
| Syphilis (early) | 11.6 2 cases ▼ 56% | 26.4 | 16 |
| Syphilis (late/unknown) | 11.6 2 cases ▼ 74% | 44.3 | 29.5 |

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 Robertson County, chlamydia has risen from 537.1 to 544.4 per 100,000 (1%), gonorrhea has fallen from 226.8 to 179.5 per 100,000 (21%), and P&S syphilis has risen from 5.9 to 17.5 per 100,000 (197%).

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 Robertson County.
Local HIV snapshot
Robertson County HIV care continuum (2023)
Among Robertson County residents living with HIV, 73.9% are in care · 52.2% 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 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 Robertson County tests for syphilis.

Data & references
Local context
South Main Street runs through the heart of Calvert past the old courthouse and Citizens Bank & Trust, anchoring a town where nearly half of residents rent rather than own. Many of them younger adults still piecing together a stable foothold, with typical monthly rent that leaves little slack in the budget for anything that feels optional. That economic reality shapes how people approach health care. With unemployment running high and fewer than two-thirds of residents actively in the workforce, a trip to a clinic isn't just a scheduling question: it's a calculation of time, gas, and whether a fee-based visit is manageable this month.
The options listed on this page vary in cost and sliding-scale availability, which matters in a community where high earners are genuinely rare and a household's margin is thin. Young adults in their late teens and twenties, the years when new relationships and life transitions make routine screening most relevant, are navigating those same pressures while often being the least likely to have a regular doctor prompting the conversation. Every visit requires a vehicle and a committed block of time out of the day. Knowing that in advance (which option is closest, what it costs, whether afternoon hours are available) is what converts a plan into a drive that actually happens.
Getting there
At 4.13/20 on the EPA walkability index, day-to-day errands in Calvert 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.
