You don’t have to keep wondering.

Maybe it was one night you’re not sure about. Maybe a partner said something. Maybe you just feel off and can’t stop thinking about it. Whatever brought you here, the fastest way to make the worry stop is to know. Most people who test come back negative – and the ones who don’t are treated quickly and quietly. Either way, you’ll be okay.

If something comes back positive

You won’t be left alone with a result. A member of our care team calls you, explains what it means in plain language, and sets up a consultation with a physician. Depending on the infection, care may be a prescription sent to the pharmacy you choose, an in-person visit for an injection, or a specialist referral – the physician explains which and helps you get there.

STDs in San Antonio: what the numbers say

San Antonio ranks 22nd among the 100 largest U.S. cities for sexually transmitted infections, and Bexar County reports more than 20,000 new chlamydia, gonorrhea and syphilis cases a year. Most of those infections cause no symptoms at all, which is the case for a routine test when you feel fine, not just when something seems wrong.

1,182chlamydia, gonorrhea and syphilis cases per 100,000 people in San Antonio22nd highest of the 100 largest U.S. cities · U.S. rate: about 600
14,191chlamydia cases reported in Bexar County in a single yearplus 6,622 cases of gonorrhea
3rdBexar County's rank in Texas for chlamydia, gonorrhea and syphilis casesper San Antonio Metro Health · Texas reported about a quarter of all U.S. congenital syphilis cases in 2022

The people hit hardest are the ones least likely to have a doctor to call. Texas has the highest share of uninsured residents in the country, and Bexar County's rate runs above the state average, with the South and West sides carrying the most of it. San Antonio Metro Health runs free STI testing at its clinic and on a mobile unit, and that is a real option if cost is the only barrier, but it means clinic hours, a wait, and a visit that goes on file with the clinic.

That is who we built this for. No insurance, no referral, no exam, one flat price, twelve places to go inside San Antonio and eight more around it, and a result in your private account in 1–2 business days. If something comes back positive, our care team calls you and, for most infections, treatment is a short prescription.

Questions people in San Antonio ask us

Is the 11212 SH 151 location open on Saturday?

No. This location is open weekdays 7 am to 4 pm, weekdays only. If you need a Saturday, Fredericksburg Road in the Medical Center, Loop 1604 East, I-35 South and West Military Drive all open Saturday morning; the San Antonio page lists every location by area. Order first so your lab order is waiting when you arrive.

What do I need to bring to 11212 SH 151?

Nothing but yourself. Your lab order is already at the test center; you sign in at the kiosk with your first name, last name and date of birth. No ID check, no paperwork, no payment at the lab, and no insurance card, because nothing is billed to insurance. The charge on your card shows as RSC Health.

Is there free STD testing in San Antonio?

Yes. San Antonio Metro Health offers free STI testing at its clinic and on a mobile unit that moves around the city, and University Health has low-cost sexual health services. If cost is the only thing stopping you, use them. The trade-offs are clinic hours, a wait, a visit that goes on file with the clinic, and results that can take longer. We are a paid service, and what you pay for is speed and privacy: order today, go to any of our twelve labs without an appointment, no exam, nothing billed to insurance, and a result in your own account in 1–2 business days.

Can I get an STD test at CVS or Walgreens in San Antonio?

CVS MinuteClinic locations in San Antonio do offer STD testing, but it is a clinic visit: you book, see a provider, the visit is billed to insurance or paid out of pocket at clinic prices, and the visit goes on file with the clinic. Walgreens sells at-home collection kits you mail in. With us there is no exam and no appointment; the doctor's order is included, you give the sample at a lab in about five minutes, and the charge on your card shows as RSC Health.

How much does an STD test cost in San Antonio?

One flat price that includes the doctor’s order, the lab visit and your results – no facility fees, no separate lab bill and nothing billed to insurance. Call (866) 872-1888 and a care advisor will quote it in about a minute, or see the Tests & Pricing page if you prefer to order online.

Which San Antonio lab is closest to downtown or the Pearl?

The Broadway location in Alamo Heights is the closest to downtown, the Pearl, Mahncke Park and Olmos Park, about ten minutes up Broadway. From the Medical Center or UTSA, Fredericksburg Road is closer; from Southtown or the South Side, Southcross Boulevard or I-35 South.

Can I get tested on a Saturday in San Antonio?

Yes. Five San Antonio locations open Saturday mornings: Fredericksburg Road in the Medical Center, Loop 1604 East, Broadway in Alamo Heights, West Military Drive, and I-35 South. Check the hours on each location's page, and order online or call first so your lab order is waiting.

Do I have to live in Bexar County to use these labs?

No. Anyone can use any location, and people come in from Comal, Guadalupe, Kendall, Medina, Wilson and Atascosa counties every day. If New Braunfels, Boerne, Seguin, Schertz, Live Oak or Pleasanton is closer to home or work, each has its own page with addresses and hours.

Will my San Antonio employer, school or parents find out?

No. We never bill insurance, so nothing appears on a family plan or military dependent statement, and we never mail anything. Your results are posted only to your password-protected account, the lab staff see a lab order rather than a reason, and the charge on your card reads RSC Health.

Where is the closest place to get an STD test near me in San Antonio?

Once you’ve ordered, this location takes about 5 minutes – no appointment needed. Order online or call first so your lab order is waiting when you arrive; there are other San Antonio locations listed below if another one is closer.

What if I’m too embarrassed to go in?

You don’t have to explain anything at the lab. They see a lab order, take a small sample, and you leave. Nobody asks why you’re there, and to the other people in the waiting room it’s a routine lab visit – our partner labs collect samples for many kinds of testing.

How soon after exposure can I test?

It depends on the infection – some show up in days, others take a few weeks. Call us and we’ll tell you the right timing for your situation so you don’t get a false “all clear.”

What if it’s positive?

Most STDs are cured with medication, and the rest are managed with treatment that lets you live normally. Our care team calls you, explains the result in plain language, and sets up a physician consultation – a prescription, an in-person visit or a referral, depending on the infection.

Do I need an appointment or a doctor?

No. The doctor’s order is included when you order, and every location takes you without an appointment once you’ve ordered.

Will this show up on my insurance?

No. We never bill insurance, so nothing goes to your insurer and nothing appears on a parent’s or spouse’s insurance statement.

How fast are results?

Most results are ready in 1–2 business days and are posted to your private online account. Results are never mailed or texted.

Ready when you are.
