Zero-Fee Care Runs Across Every Service Here
Texas Specialty Clinic funds the full scope of its services (testing, STI treatment, PrEP, PEP, hepatitis B and C treatment, HIV medical management, and mpox and HPV vaccination) at no charge. No copay tier, no balance at checkout; the no-fee structure is clinic-wide, not limited to a subset of visits.
Spanish Is a Full Clinical Language Here
Spanish is a primary care language at Texas Specialty Clinic in San Antonio, not a supplemental channel. Medication adherence counseling, PrEP education, and HIV prevention discussions all run in Spanish: meaning nuanced conversations about dosing, adherence schedules, and risk reduction happen in the language without a separate facilitation layer.
PrEP and PEP Without the Gap Between Clinics
When PrEP or PEP requires specialist-level prescribing and a patient has to pursue it through a separate provider, the gap between exposure and prescription widens. Texas Specialty Clinic prescribes both directly, keeping PrEP initiation and PEP access inside the same appointment where testing and counseling happen.

Beat AIDS in San Antonio offers free HIV and hepatitis B testing alongside syphilis screening, with sliding-scale fees on broader services and both Medicaid and private insurance accepted. Walk-ins welcome, no appointment necessary.

Every Visit Lands at Zero Dollars
A fee at the door, or a bill arriving weeks later, is what turns a same-day result into a skipped follow-up and an untreated infection that compounds. Beat AIDS removes that entirely: HIV and STI testing carry no charge, so the cost of knowing never becomes the reason someone waits.
Spanish Care Beyond Scheduling Logistics
Clinics that serve Spanish-speaking patients often stop at translated forms or a bilingual front-desk staffer who hands things off. Beat AIDS delivers care (counseling, results, treatment conversations) in Spanish directly, so nothing critical gets flattened in translation.
PrEP and PEP Prescribed and Monitored On-Site
Beat AIDS prescribes both PrEP and PEP in-house, then manages the ongoing lab work and dosing follow-up that make either regimen actually function: PrEP requires periodic HIV testing and kidney-function checks to stay safely on it, and that monitoring happens at the same clinic, not across separate providers.

Spanish On-Site, With Real Clinical Follow-Through
Spanish-language care is built into every appointment at Planned Parenthood South and interpretation services extend that to other languages: meaning a diagnosis, a treatment plan, and a prevention conversation all move forward without a language gap slowing clinical decisions.
Title X Covers Minors With Legal Confidentiality
As a Title X-funded site, Planned Parenthood South Texas provides legally confidential family planning and STI services to minors, which means a young person's visit, results, and treatment are protected by federal law, not just clinic policy.
PrEP, PEP, and DoxyPEP Together in One Practice
Many STI clinics prescribe PrEP but don't extend their prevention formulary to PEP or DoxyPEP; Planned Parenthood South Texas carries all three, so the right prevention strategy (whether ongoing, situational, or post-bacterial-exposure) is decided and prescribed in the same clinical relationship.

CentroMed in San Antonio tests for HIV, syphilis, gonorrhea, chlamydia, and hepatitis A, B, and C on a sliding-scale fee open to everyone, with same-visit treatment for bacterial STIs, and the full clinic runs in Spanish.
Read full overviewShow less
Full Hepatitis Panel Alongside the Standard Four
CentroMed tests for hepatitis A, B, and C in addition to the standard bacterial and viral panel, which means a single visit can produce a complete picture of bloodborne and sexually transmitted exposure, rather than leaving hepatitis status as an open question after you leave.
PrEP and PEP Managed Here, Not Chased Down Elsewhere
Without PrEP or PEP access at the same clinic where you're tested, you absorb the cost (in time, appointments, and follow-through) of tracking down a prescriber separately. CentroMed holds both, so prevention doesn't fall through the gap between a test result and a prescription.
Care and Counseling Conducted in Spanish
CentroMed delivers care in Spanish, which means HIV test counseling, treatment conversations, and prevention guidance, including PrEP education, happen in the same language without anything filtered through a second person or deferred to a follow-up call.
Centromed Sarah E Davidson Clinic in San Antonio earned its federally qualified designation by anchoring care for patients paying out of pocket, between coverage gaps, or stretching tight incomes. Sliding-scale fees make syphilis, gonorrhea, and chlamydia screening genuinely reachable, and no appointment is needed to get started.

Zero-Cost Care Closes the Treatment Gap
When cost enters the equation, follow-up appointments get skipped and infections go unmanaged. That gap is what University Health closes. Every service here, from the first rapid test to ongoing HIV treatment, carries no charge, so nothing in the billing process interrupts the care.
Ryan White Funding Runs Testing Through Ongoing HIV Treatment
University Health is Ryan White-funded, which means HIV care doesn't end at a confirmed diagnosis. It continues into sustained medical management at the same clinic. For someone living with HIV, that continuity eliminates the gap between detection and the sustained treatment that keeps the virus suppressed.
PrEP and PEP Prescribing On-Site in San Antonio
University Health prescribes both PrEP and PEP directly, meaning ongoing prevention medication, including the regular HIV and kidney-function monitoring that a PrEP regimen requires, is managed in-house rather than handed off elsewhere, keeping the prescription and its clinical oversight in a single place.

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.

Bexar County HIV care continuum (2023)
Bexar County recorded 22.3 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Bexar County residents living with HIV, 82.9% know their status · 77.4% are in care · 67.6% 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.
Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
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 Bexar County tests for syphilis.

San Antonio households tend to run large and close-knit, when nearly four people share a home and two out of five adults are married, health decisions rarely happen in isolation. A partner's hesitation, a parent's schedule, or a shared budget can shape whether someone books a screening or keeps putting it off. That dynamic matters here, where younger adults, people in their late teens and twenties, make up a substantial slice of Bexar County's population during the years when STI transmission peaks. Rent around a thousand dollars a month leaves real money on the table for a household already stretching across nearly four people, which means cost-accessible options aren't a convenience.
They're often the deciding factor. Workforce participation here is solid but not universal: a meaningful share of residents are between jobs or working variable hours, and the clinics on this page reflect that range of schedules. In a city where family logistics and tight budgets shape most daily decisions, a same-week appointment near San Pedro Springs Park or along the McDermott Freeway corridor is often what turns a reasonable intention into an actual result.

Confidentiality & consent in TexasMinor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
