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 put off an STD test because they do not know what the visit looks like. It is usually shorter and calmer than people expect. Most of it is a conversation, a urine cup, a swab or a small blood draw.

This guide walks through what an STD test involves, from booking to results. It also explains what a standard STD panel does and does not cover, and it points to Austin clinics where you can get tested for free or at low cost.

What you need before you go

You do not need to prepare much. A few small things make the visit smoother.

A photo ID, if you have one. Ask the clinic when you book, because requirements vary.
Insurance information, if you have it. Some clinics bill insurance and others use flat or sliding fees.
A rough timeline. Think about when you last had sex, or when a possible exposure happened. The clinician will ask.
A list of medicines and allergies. This matters if a clinician later prescribes treatment.
Your questions. Write them down. Visits go quickly and it is easy to forget them.
Time. Plan for a short visit, but leave room for paperwork and a possible wait.

For a urine test, many clinics ask you not to urinate for a short time beforehand. Ask when you book if this applies to you.

Step by step: what happens at an STD test

Step 1: Pick a clinic and book, or confirm walk-in hours

Clinics in Austin work differently. Some take walk-ins and some need an appointment. Austin Public Health lists its Sexual Health Clinic at the RBJ Health Center, 15 Waller Street, and says to schedule online or call 512-972-5430. Its page lists hours of Monday to Friday, 8 a.m. to 12 p.m. and 1 to 5 p.m. The same page says the fee for testing and treatment is $30.

Austin Public Health also notes that website content updates may be delayed. Call to confirm hours and fees before you go.

Step 2: Check in and fill out paperwork

At check-in you will give your name, contact details and payment or insurance information. You may fill out a short health form. Clinics are used to this, and what you write is part of your confidential medical record.

If you are under 18, Texas Family Code Sec. 32.003 allows a minor of any age to consent to diagnosis and treatment of reportable infectious diseases. Parent or guardian consent is not needed for that care. The same section lets a physician tell a parent or guardian about the treatment, so ask the clinic how it handles that before you share details.

Step 3: Answer the intake questions

A nurse or clinician will ask about your health and sexual history. These questions can feel personal. They are not about judging you. They decide which tests make sense for your body and your situation.

Common questions, and why they are asked:

Any symptoms right now? Symptoms change which tests are used and whether you need a provider visit instead of a routine screen.
When was your last test? This helps the clinician decide what is due.
What kinds of sex do you have? Vaginal, anal and oral sex can each involve different body sites. The CDC STI Treatment Guidelines (2021) recommend sampling the sites that were exposed, which can include the throat or rectum.
How many partners, and what protection do you use? This helps the clinician choose tests and talk about prevention options.
Any past STIs, or a partner who was told they had one? A known exposure can change the plan.
Are you pregnant or trying to be? Pregnancy changes screening and treatment options.

Answer as honestly as you can. You can skip a question or ask why it matters. The care team has heard it all, and all genders and orientations are welcome.

Step 4: Decide which tests to run

Next, you and the clinician agree on the tests. The CDC recommends different routine screening for different groups. For example, the CDC STI Treatment Guidelines (2021) recommend yearly chlamydia and gonorrhea screening for sexually active women under 25. They also recommend it for older women with risk factors, and for men who have sex with men. The CDC and the U.S. Preventive Services Task Force (USPSTF) also recommend HIV screening at least once as part of routine health care for most adults and teens.

That is where terms like std test for men and std test for women come from. The tests are mostly the same. The sample type and the extra tests can differ, as the next steps show.

Step 5: Give a urine sample, if one is used

A urine test is often used to check for chlamydia and gonorrhea. You pee into a small cup in a private restroom. It takes a minute or two. For many men this is the main sample for those two infections. Women may be offered a vaginal swab instead. The CDC guidelines describe a vaginal swab as the best sample for women, though urine can be used.

Step 6: Give a swab sample, if one is used

Swabs are cotton or soft-tipped sticks that collect a small sample. Where they go depends on your history and symptoms.

Vaginal swab. Many clinics let you collect this yourself in private. The clinician will explain how.
Throat or rectal swab. These may be offered if you have had oral or anal sex. Rectal swabs can often be self-collected too.
Swab from a sore or blister. If you have an active sore, a clinician may swab it to test for herpes or other causes.

Swabs can feel odd, but they are usually quick and should not be painful. Tell the clinician if you are uncomfortable.

Step 7: Give a blood sample, if one is used

Blood tests are used for HIV and syphilis. A clinician or phlebotomist draws a small amount from your arm, which takes a few minutes. Some HIV tests use a fingerstick instead, and some use oral fluid. A pelvic exam is not required for most routine STD testing.

The CDC lists different window periods for HIV tests. A window period is the time after exposure when a test may not yet pick up an infection. Per the CDC:

A nucleic acid test can detect HIV about 10 to 33 days after exposure.
An antigen/antibody test on a lab blood draw can detect it about 18 to 45 days after exposure.
An antigen/antibody fingerstick test can take 18 to 90 days.
Antibody tests can take 23 to 90 days.

If your exposure was recent, tell the clinician. They may suggest a different test or a repeat test later.

Step 8: Ask your questions before you leave

Before you go, confirm three things: how you will get your results, how long they usually take, and what number to call. Ask what happens if a result needs follow-up. If you are given a number to call, save it in your phone.

Step 9: Get your results

Timing depends on the test and the clinic. Some rapid HIV tests give results during the visit. Urine, swab and most blood tests are usually sent to a lab, and results come back later by phone, secure portal or a follow-up visit. Ask how your clinic does it.

If a test is positive, a clinician explains the next step. Bacterial STIs such as chlamydia, gonorrhea and syphilis, and trichomoniasis, can be cured with treatment from a clinician. HIV, herpes and HPV cannot be cured, but they are treatable or manageable with care from a clinician.

Texas requires certain results to be reported to the health department. According to Texas DSHS (Texas Notifiable Conditions, 2026), these include chlamydia, gonorrhea, syphilis and HIV. This is a public health tracking step done by the clinic or lab.

Step 10: Plan for partners and follow-up

If a result is positive, the clinician will talk about telling recent partners so they can be tested. According to CDC's legal status page for Texas, state rules allow clinicians to provide treatment for the partners of an established patient. This is called expedited partner therapy. Ask the clinician whether it applies to your situation. Some infections also call for a repeat test a few months after treatment, so ask about that too.

What a full STD panel is and is not

You may hear people ask for a full std panel. There is no single official panel that covers every infection. What a clinic calls a panel is simply the group of tests it offers together, and the group differs from place to place.

For example, Austin Public Health says its standard tests are HIV, syphilis, gonorrhea and chlamydia. It adds that it can only test for genital herpes if you have active symptoms. The University Health Services clinic at UT Austin lists chlamydia, gonorrhea, HIV and syphilis. Kind Clinic lists walk-in testing for gonorrhea, syphilis, chlamydia, HIV and hepatitis C.

A few other points to know:

Herpes. The CDC does not recommend routine herpes blood testing for people without symptoms, which is why many clinics test only when a sore is present.
HPV. HPV testing is not part of a standard STD panel. For women, HPV tests are tied to cervical cancer screening. The CDC says there is no approved HPV test to look for the virus in men.
Other infections. Hepatitis B and C, trichomoniasis and mpox are not always included. Ask whether they are offered and whether they apply to you.

So when you book, ask exactly which infections the visit covers. A clinician can tell you what is and is not included.

Does an STD test differ for men and for women?

The basic steps are the same. The main differences are the samples and the extra questions.

An STD test for men often uses a urine sample for chlamydia and gonorrhea, plus blood tests for HIV and syphilis. Throat or rectal swabs may be added based on sexual contact.
An STD test for women often uses a vaginal swab, which can usually be self-collected. Blood tests for HIV and syphilis are similar. Pregnancy questions come up too.
Trans and nonbinary people are best served by testing based on the body parts and sexual contact involved, not gender label. Tell the clinician what is relevant, and ask for the sites to be sampled that match your anatomy.

Texas law also sets prenatal screening. Under Texas Health and Safety Code Sec. 81.090, syphilis, HIV and hepatitis B tests are done at the first prenatal visit, and syphilis and HIV tests again in the third trimester. A pregnant patient may object to the HIV tests but not the syphilis tests.

Tips and common mistakes to avoid

Do not skip the honest answers. Leaving out a type of sex or a symptom can mean a site goes untested.
Do not assume one test covers everything. Ask what is included before you leave.
Mind the timing. A test too soon after exposure can miss an infection. Ask about repeat testing.
Do not wait for symptoms. Many STIs cause no symptoms at all, which is why the CDC recommends routine screening for some groups.
Do not use leftover antibiotics. Treatment should come from a clinician after a diagnosis.
Do not skip the results call. Make sure the clinic has a working phone number for you.
Check clinic rules first. Walk-in availability and eligibility differ. For example, the UT clinic serves UT Austin students, and its drop-in is for people without symptoms.

What results can and cannot tell you

A negative result means the test did not find that infection in the sample at that time. It may be less certain if the exposure was recent, because of the window periods above. No test is perfect, so a clinician can advise whether to repeat it.

A positive result means the test found signs of an infection. A clinician will usually confirm or explain it and discuss options, including treatment they prescribe. Only a clinician can tell you what your own results mean.

Whatever comes back, you have information, and you can act on it.
