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.

Many people in Austin want to get tested and get answers quickly. Some tests can give a result in the same visit. Others need a lab and take a few days.

This guide walks you through the process step by step. It explains which tests can be quick, how long STD test results usually take, and how to choose a clinic here in Austin.

Testing is a routine part of health care. People of every gender and orientation get tested, for many reasons.

What can and cannot be done the same day

Not every test works the same way. The speed depends on the method.

Tests that can give a result at the visit

Rapid HIV tests. The CDC describes rapid HIV tests as tests that can return a result in about 30 minutes or less. Austin Public Health lists a free 20-minute walk-in express HIV testing service through its Red Ribbon program.
Rapid syphilis tests, where offered. Some clinics offer them and many do not. The local fact sheet does not confirm rapid syphilis testing at any Austin site, so ask the clinic before you go.

Tests that usually need a lab

Chlamydia and gonorrhea. These are usually checked with a nucleic acid amplification test (NAAT), which the CDC STI Treatment Guidelines (2021) recommend. The sample goes to a lab, and results commonly take about 1 to 3 days. Your clinic can give you its own timeline.
Standard syphilis blood tests. These are usually sent to a lab too.
Lab-based HIV tests. A clinic may draw blood and send it out instead of using a rapid test.

So the answer to "how long do STD test results take" is: it depends on the test. A rapid HIV test may take minutes. Lab-based tests often take a few days.

Materials you will need

You do not need much. Gather these before you go.

A photo ID, if you have one. Ask the clinic what it needs.
Your insurance card, if you have insurance. Some clinics must bill insurance first. Others have sliding fees or free testing.
A phone number where you can be reached privately for results.
A list of any symptoms and when they began. Include any recent exposure dates you remember.
A list of medicines you take and any allergies.
Payment, if the clinic charges a fee. Call ahead to confirm the amount and the payment types accepted.
A few questions written down (examples are in Step 5).

Step-by-step: how to get tested quickly in Austin

Step 1: Decide what you want to be tested for

The CDC STI Treatment Guidelines (2021) and the USPSTF both describe who benefits from routine screening. The right tests depend on your age, partners, symptoms and health history.

If you are not sure, tell the clinician what has happened and ask which tests make sense. That is a normal question, and nobody will judge you for asking.

The CDC also has a locator at gettested.cdc.gov that lists testing sites by ZIP code.

Step 2: Think about timing

A test can only detect an infection after enough time has passed. This is called the window period, and it differs by infection and by test.

For HIV, the CDC says a lab test on blood from a vein can usually detect HIV about 18 to 45 days after an exposure. It says antibody tests can take longer, from about 23 to 90 days. Rapid tests use a fingerstick or oral fluid, and the CDC notes that they may take longer to detect HIV than a lab test on blood from a vein.

If you test early, a clinician may suggest testing again later. That is a normal part of care. For other infections, ask the clinician what the CDC guidance means for your situation.

Step 3: Pick a place that fits your schedule

Walk-in sites can be the fastest route. Appointment sites can still be quick, but you need to plan ahead. Here are the Austin options from the local fact sheet.

The Austin Public Health website says its content updates may be delayed. Confirm hours and fees by phone before you go.

Step 4: Call ahead and confirm the details

A two-minute call can save a trip. Here is what to confirm.

Are walk-ins accepted today, and until what time?
Which tests do you offer at this location?
Do you offer rapid tests, and which ones?
What will it cost, and what payments do you accept?
How will I get my results, and how long does it usually take?

Hours matter. Austin Public Health's clinic lists Monday to Friday, 8 a.m. to 12 p.m. and 1 to 5 p.m. Kind Clinic lists weekday hours that run later on Wednesday and Thursday, and certain Saturday hours. Its walk-in testing hours differ from its general hours. Kind Clinic is also closed on all observed holidays and on the first Friday of every month.

Symptoms can change where you should go. The UT drop-in is for people without symptoms, and people with symptoms need a provider appointment. Austin Public Health says it can only test for genital herpes when there are active symptoms.

Step 5: At the visit, tell the clinician what matters

Share your symptoms, recent partners and any past results. You can also ask:

Which of my results could come today, and which will take longer?
Should I plan to test again later because of timing?
What happens if a test needs follow-up?

Depending on the infection, testing may use a urine sample, a swab, a blood draw or a fingerstick. Many swabs can be collected by you in private.

Step 6: Learn how you will get your results

Before you leave, ask how and when the clinic will contact you. Ask whether they will call, text or use a patient portal. Confirm that the number on file is one you can answer safely.

Write down the date you expect results. If that date passes, call the clinic.

Step 7: Plan for what comes next

Whatever the result, a clinician can explain the next steps.

Chlamydia, gonorrhea, syphilis and trichomoniasis are curable with treatment prescribed by a clinician.
HIV, herpes and HPV are not curable, but they are treatable or manageable with care from a clinician.

If a result means a partner should be checked, ask the clinician how to tell them. Under Texas rules described by the CDC in its legal status summary for expedited partner therapy, a clinician may be able to prescribe treatment for the partner of an established patient. Ask your clinician whether that applies.

How long do STD test results take?

Here is a general guide. Your clinic's timeline is the one that counts.

Rapid HIV test: often about 20 to 30 minutes, according to the CDC and the Red Ribbon program.
Chlamydia and gonorrhea (NAAT): usually about 1 to 3 days.
Syphilis blood test: often a few days if sent to a lab. Ask whether a rapid test is available.
Lab-based HIV test: usually a few days. Ask the clinic.

A fast STD test result does not mean a less careful test. Rapid and lab tests are built for different settings. A clinician can tell you which one fits your situation.

Tips for a smoother visit

Go early in the day. Walk-in lines can build up, and clinics may stop accepting walk-ins before closing.
Avoid urinating for about an hour before a urine test, if the clinic asks. Follow the clinic's own instructions.
Bring a list of questions. It is easy to forget them in the room.
Ask about free or low-cost options. Austin has several, listed above.
Keep your results. Ask for a copy or portal access.

If you are under 18, Texas Family Code Sec. 32.003 lets a minor of any age consent to diagnosis and treatment of reportable infectious diseases. That includes reportable STIs and HIV. The same law allows a physician to tell a parent or guardian about the treatment, so ask the clinic about its practice before your visit.

Common mistakes to avoid

Assuming one quick test covers everything. A rapid HIV test checks for HIV only. Ask what else is included.
Skipping the timing question. A very recent exposure may mean a retest is worth discussing with a clinician.
Arriving without calling. Hours, walk-in rules and test menus differ by site, and the Austin Public Health page may be out of date.
Not asking how results arrive. Missed calls are a common reason people wait longer than they need to.
Waiting because of embarrassment. Clinicians see this every day. Testing is routine care, not a judgment.
Leaving without a follow-up plan. Ask what happens next, whatever the result.

What results can look like

Results are reported as negative or positive for each infection tested. Test accuracy depends on timing and the type of test, so a negative result may not rule out a very recent exposure. A clinician can explain what your result means for you.

After a test that finds a reportable infection, the lab and clinic report it to public health, as Texas DSHS requires. The Texas DSHS notifiable conditions list for 2026 includes chlamydia, gonorrhea, syphilis and HIV.

If a result needs follow-up, the clinic will explain the steps. Treatment is whatever a clinician prescribes for you.

Why testing matters in Travis County

Texas DSHS reported 9,452 chlamydia cases in Travis County in 2022, a rate of 712.6 per 100,000 people. For the same year, the Texas DSHS STD Surveillance Report gives a statewide chlamydia rate of 519.9 per 100,000. Travis County also had 4,661 gonorrhea cases in 2022, a rate of 351.4 per 100,000, compared with 207.0 for Texas.

These numbers reflect reported cases, which depend partly on how much testing happens. They are one reason routine testing is useful. They are not a reason to worry.

Other free options

Texas DSHS runs Test for Texas, which offers free mail-order self-testing for HIV, syphilis, gonorrhea and chlamydia at testfortexas.org. Mail-order results will not be same-day, since the process takes time. It can still be a private route if getting to a clinic is hard.

Your next step

If you want answers quickly, a walk-in site or the free Red Ribbon express HIV service is a good place to start. Call first, bring your questions, and ask how and when you will hear back.
