This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

San Antonio has more than one kind of STD clinic. Some are run by the city. Some are nonprofits that focus on HIV and sexual health. Some are community health centers that treat a wide range of needs. Planned Parenthood is another option.

Each kind works a little differently. They differ on cost, whether you need an appointment, whether you need photo ID, and whether treatment is offered on site. This page lays those differences side by side so you can pick the one that fits your situation.

It does not tell you where you personally should go, and it cannot say anything about your health. A clinician or a test is the only way to learn that. If you want a longer list of places to get tested, see our guide to where to get tested in San Antonio.

Why the choice of clinic matters in Bexar County

Bexar County reports more gonorrhea and syphilis than the state as a whole. The Texas Department of State Health Services (DSHS) 2022 STD Surveillance Report lists 5,983 gonorrhea cases in Bexar County, a rate of 290.5 per 100,000 people. The statewide DSHS rate for the same year was 207.0 per 100,000.

For primary and secondary syphilis, the same report lists 500 Bexar County cases in 2022, a rate of 24.3 per 100,000. The Texas rate that year was 15.5 per 100,000.

The same report counts 12,305 chlamydia cases in Bexar County in 2022. It does not print a county chlamydia rate, so no rate is given here. For HIV, CDC surveillance tables for 2024 list 373 new diagnoses in Bexar County, a rate of 21.1 per 100,000 people aged 13 and older.

These numbers are not a reason for alarm. They are a reason to know where testing is easy to get. Many infections cause no symptoms, so testing is how people find out.

The four main types of option

1. The public health department

The San Antonio Metropolitan Health District, known as Metro Health, runs the Metro Health STI Walk-In Clinic at 512 E. Highland, Suite 150, San Antonio, TX 78210. The phone number is 210-207-8830. University Health lists the clinic as offering STI and HIV testing, treatment and counseling.

This is the main city option for health department STD testing. Metro Health lists these hours:

Monday to Thursday, 7:45 a.m. to 4:30 p.m., with the latest check-in at 3 p.m.
Friday, 7:45 a.m. to 12:00 p.m., with the latest check-in at 10:30 a.m.
Check-in may close early when the clinic is at capacity.

Metro Health lists a $15 office visit administrative fee, and says other fees vary by service. It also lists who the clinic serves: residents of San Antonio and Bexar County, and people who have no other means of getting STI services. A current photo ID is required, and the clinic does not offer anonymous testing.

Metro Health also runs a separate PrEP Clinic at the same address, with its own number, 210-207-7292. Its page says a nurse practitioner evaluates PrEP candidates, labs are done in the clinic, and a PrEP Navigator helps with counseling and insurance or financial questions. Walk-ins are accepted, and Metro Health encourages appointments. The page does not list a price and says the PrEP team helps regardless of financial situation.

2. HIV and sexual health nonprofits

Several San Antonio nonprofits focus on HIV and STI testing. Four are covered here.

San Antonio AIDS Foundation (SAAF), 818 E. Grayson Street, (210) 225-4715. SAAF lists rapid HIV, syphilis, gonorrhea and chlamydia testing. It says screening and confirmatory services are free and no appointment is needed. Gonorrhea and chlamydia results come back in 7 to 10 days through the DSHS lab. SAAF also lists PrEP and doxy-PEP.
Alamo Area Resource Center (AARC), 303 N. Frio, (210) 625-7200. AARC lists free testing for HIV, hepatitis C, syphilis, gonorrhea and chlamydia, with rapid fingerstick tests for HIV, syphilis and hepatitis C. Walk-ins are listed Monday to Friday, 8 a.m. to 4:30 p.m., and Wednesday until 8 p.m. AARC also lists PrEP and PEP.
Kind Clinic, 730 Isom Road, run by Texas Health Action. Kind Clinic lists HIV and STI testing, STI treatment, HIV care, PrEP and PEP, with free walk-in testing. Clinic hours are Monday, Tuesday and Friday 9 a.m. to 5 p.m., Wednesday and Thursday 9 a.m. to 8 p.m., and the second and fourth Saturdays 9 a.m. to 2 p.m. Its locations page says walk-in testing hours differ from clinic hours, so call before you go. The only number listed is the general support line, 833-937-5463. Kind Clinic says doxy-PEP is available to its own patients only.
BEAT AIDS, 210-212-2266. BEAT AIDS lists free, confidential HIV testing and PrEP, plus confidential testing and treatment for common STIs. Its website does not say which of its San Antonio locations does the testing, and it does not say whether walk-ins are accepted. Call first.

3. Community health centers

Community health centers treat many health needs, and STD care is one of them. They tend to use income-based pricing.

CommuniCare Apollo Wellness Clinic, 6511 W Loop 1604 N, Ste. 105, (726) 224-3438. CommuniCare lists STD and HIV screening and testing, and PrEP. Hours are Monday to Friday, 8 a.m. to 5 p.m. It offers a sliding fee discount for self-pay patients with family income under 200% of the federal poverty guidelines. Its page does not say whether walk-ins are accepted.
CentroMed, 210-922-7000. CentroMed lists screening and treatment for sexually transmitted diseases under its women's services. It uses a sliding fee scale based on income and family size, and says it does not deny care for inability to pay. It has multiple clinics, and its page does not say which ones offer STD care. Ask when you call.

4. Planned Parenthood

Planned Parenthood South Texas operates health centers in San Antonio. Planned Parenthood is a national health care organization that lists sexual and reproductive health services, which can include STI testing and treatment depending on the center.

The organization's own San Antonio pages were not available when this page was prepared. As a result, its current services, prices, hours and walk-in policy are not confirmed here. Before you go, check with the nearest center about which tests it offers, what it charges, and whether you need an appointment. This page does not recommend or endorse any provider, and it has no affiliation with Planned Parenthood or any clinic named here.

Pros and cons of each option

Public health department

Pros: Testing and treatment are listed at one address. The fee is low and published. A PrEP Clinic is in the same building. The clinic is run by the city, so it is accountable to the public.

Cons: Photo ID is required and anonymous testing is not offered. Eligibility is tied to living in San Antonio or Bexar County, or having no other way to get STI care. Hours are limited, Friday ends at noon, and check-in can close early.

HIV and sexual health nonprofits

Pros: Testing is free at SAAF, AARC, Kind Clinic and BEAT AIDS, and these organizations focus on sexual health and HIV. SAAF, AARC and Kind Clinic list walk-in testing. Rapid tests can give some results quickly. PrEP, PEP and doxy-PEP are listed at several of them.

Cons: Treatment for bacterial STIs is listed only at Kind Clinic and BEAT AIDS. At SAAF and AARC, a positive result may mean a referral elsewhere. Gonorrhea and chlamydia results at SAAF take 7 to 10 days. Doxy-PEP access varies, and at Kind Clinic it is for its own patients only.

Community health centers

Pros: They can serve as a regular source of care. Income-based pricing can lower costs, and you can address other health needs in the same visit.

Cons: Cost is not free, and you need to qualify for the sliding scale. Walk-in policies are not stated. Not every location offers every service.

Planned Parenthood

Pros: It is a well-known national organization, and its centers focus on sexual and reproductive health.

Cons: Its San Antonio details are not confirmed on this page, so you will need to call to learn current services, prices and hours.

Best for, by situation

You want testing and treatment in one visit: Metro Health, Kind Clinic or BEAT AIDS list both. Confirm hours and walk-in policy first.
You want free testing and no cost barrier: SAAF, AARC, Kind Clinic and BEAT AIDS list free testing.
You want results from a fingerstick test: AARC lists rapid HIV, syphilis and hepatitis C tests.
You are interested in PrEP: The Metro Health PrEP Clinic, SAAF, AARC, Kind Clinic, BEAT AIDS and CommuniCare all list PrEP. Metro Health has a navigator to help with insurance and financial questions.
You want to ask about doxy-PEP: SAAF lists it. Kind Clinic offers it to its own patients. The CDC published doxy-PEP guidance in 2024, and a clinician can tell you whether it fits your situation.
You want an ongoing health home: CommuniCare and CentroMed use sliding fees for income-based pricing.
You are a teen: Texas Family Code Section 32.003 lets a minor of any age consent to diagnosis and treatment of a reportable infectious disease, including reportable STIs and HIV. Parent or guardian consent is not required. The statute also allows a physician to tell a parent or guardian, so a provider may not keep it fully private. Ask about the clinic's practice before your visit.
You cannot get to a clinic during open hours: Test for Texas, run by DSHS, mails free at-home kits for HIV, syphilis, gonorrhea and chlamydia to anyone in Texas aged 13 or older. Orders are placed at testfortexas.org, and results arrive in a secure portal seven business days after the sample reaches the lab.
You are pregnant: Texas Health and Safety Code Section 81.090 calls for syphilis, HIV and hepatitis B tests at the first prenatal visit, with syphilis and HIV tests again in the third trimester. A pregnant person may object to the HIV tests but not the syphilis tests. Metro Health says syphilis testing for pregnant women is available at its clinics.

A few things to know before any visit

Texas requires clinics and labs to report certain infections to public health authorities. According to the DSHS Texas Notifiable Conditions list for 2026, these include chlamydia, gonorrhea, syphilis and HIV. Reports go to health authorities for tracking and follow-up.

Texas has no HIV-specific or STD-specific criminal exposure law, according to the CDC's 2023 analysis. General criminal laws can still apply, so if you have legal questions, an attorney or a legal aid service can help.

For partners, the CDC lists Texas as allowing expedited partner therapy through administrative rules. A clinician can prescribe treatment for partners of an established patient in some cases. Ask your clinician whether this applies to you.

Some questions are worth asking whichever clinic you choose:

Which tests do you run, and which body sites can you test?
How and when will I get results?
What will I pay today, and could there be a separate lab fee?
Can you treat an infection on site, or will you refer me?
Do you offer services in my language?

The CDC explains that the right time to test after an exposure depends on the infection and the test. A clinician can tell you whether to come back for another test later.

Verdict

No single clinic is best for everyone. The answer depends on what you need most.

If you want a published, low fee and a city-run clinic that lists both testing and treatment, Metro Health is a strong starting point, as long as you have photo ID and can meet its hours. If cost is the main concern and you want a sexual health specialist, the nonprofits are the better fit. SAAF, AARC and Kind Clinic list free walk-in testing. Kind Clinic and BEAT AIDS also list treatment.

If you want a long-term health home with income-based pricing, CommuniCare or CentroMed may fit. Planned Parenthood is a reasonable option to consider, but its details are not confirmed here. Call the center first.

Whichever you choose, it helps to call ahead. Hours, walk-in rules and fees can change, and several clinics do not publish their policies.
