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.

An STD test is usually shorter and less awkward than people expect. Most visits come down to a few questions, a urine cup or a quick swab, and sometimes a blood draw.

This guide walks through each stage in order, so you know what an STD test involves before you go. It also covers what a full STD panel is and is not, and which Dallas clinics to contact.

Why this matters in Dallas

Texas DSHS reports that Dallas County had 22,073 chlamydia cases in 2022, a rate of 848.7 per 100,000 people. The statewide rate that year was 519.9 per 100,000. The same DSHS report counted 10,696 gonorrhea cases in the county, a rate of 411.3 per 100,000.

These numbers mostly reflect how common testing and reporting are, and that many infections have no symptoms. They are a good reason to treat testing as routine health care.

What you need before you go

You do not need to prepare much. A short checklist helps the visit go smoothly.

Photo ID and insurance card, if you have them. Ask the clinic what it requires when you book. Some clinics accept Medicaid or offer sliding scale fees.
A list of your medicines. Include anything you take regularly, since a clinician may ask.
Rough dates. Note when you last had sex and any recent symptoms, such as discharge, sores, itching or pain when you urinate.
Your questions. Write them down so you do not forget them in the room.
A way to receive results. Know which phone number or patient portal the clinic will use.

Ask the clinic whether you should avoid urinating for a while before the visit. Some clinics want a first-catch urine sample, and the instructions vary.

Step 1: Choose a place and book

Many Dallas clinics ask for an appointment, and some take walk-ins. Check before you go, because policies change.

Sexual Health Clinic (Dallas County Health and Human Services). It is at 2377 N. Stemmons Freeway, 1st Floor, Suite 100, and the phone is (214) 819-1819. The county page says appointments are required and that same-day or next-day appointments are offered. It also says routine testing without symptoms is directed to the DCHHS Mobile Medical Unit. The county page lists no fees. The CDC GetTested listing says Medicaid is accepted and to contact the organization about eligibility. Read the clinic page for current hours.
Resource Center Health (Nelson-Tebedo clinic). It is at 2603 Inwood Rd., phone 214.528.2336. Its testing page lists confidential rapid HIV antibody, early HIV RNA and syphilis tests as free. It lists gonorrhea and chlamydia testing as free with a $40 office visit. Its page says to request an appointment online and does not mention walk-ins. See the Resource Center testing page.
Prism Health North Texas, Oak Lawn Health Center. It is at 2801 Lemmon Ave, Suite 200, phone 214-521-5191. Prism says it uses sliding fee rates based on household income and size, and accepts Medicaid, Medicare, CHIP and most private insurance. It says to schedule ahead, with same-day and walk-in slots for urgent issues depending on availability. Its locations page also lists centers in Oak Cliff, South Dallas and elsewhere.
AHF Healthcare Center - Dallas. It is at 7777 Forest Ln Ste B 122, phone (972) 383-1060. The CDC GetTested listing says an appointment is not required and that fees are on a sliding scale.
Neighborhood Medical Center. It is at 5917 Belt Line Rd, phone (972) 726-6464. The CDC GetTested listing says an appointment is not required and that insurance and a sliding scale are accepted.

Language support varies by clinic. The Resource Center's PrEP program page says "se habla español." For any other clinic, ask when you call whether interpreter services are available.

Step 2: Check in and answer the intake questions

You will fill out a form or talk with a nurse or clinician. The questions can feel personal. They have a practical purpose, and the answers stay in your medical record.

You may be asked about:

Symptoms. This tells the clinician which sites to check and which tests make sense.
Types of sex and sites of contact. Vaginal, anal and oral sex can each expose different body sites. The CDC STI Treatment Guidelines (2021) describe collecting samples from the throat, rectum or genitals depending on the exposure.
Number and gender of recent partners. This helps the clinician decide how often you might be tested. It is not a judgment.
Condom or barrier use. This helps the clinician understand which exposures happened.
Past STI history and vaccinations. Past infections can matter, and so can vaccines such as HPV.
Pregnancy or plans for pregnancy. Some infections affect pregnancy, and some medicines need to be chosen with that in mind.
Medicines, allergies and PrEP or PEP use. These affect which tests and follow-up are suitable.

You can answer honestly without worrying about being judged. Clinicians ask these same questions of everyone. If a question does not apply to you, say so.

Step 3: Decide what to test for

The clinician will suggest tests based on your answers. The CDC says screening advice depends on age, anatomy and risk.

STD test for women. The CDC recommends yearly chlamydia and gonorrhea screening for sexually active women under 25. It also recommends it for older women with risk factors, such as a new partner or a partner with other partners.
STD test for men. The CDC recommends at least yearly syphilis, HIV, chlamydia and gonorrhea screening for gay, bisexual and other men who have sex with men. Testing at each body site of contact is advised. The CDC suggests more frequent screening for some people. For heterosexual men, your clinician will advise based on symptoms and exposure.
HIV. The CDC recommends that everyone aged 13 to 64 be tested for HIV at least once, and more often if there are ongoing exposures.
Pregnancy. The Texas Health and Safety Code, Section 81.090, calls for syphilis, HIV and hepatitis B testing at the first prenatal visit. It also calls for syphilis and HIV testing in the third trimester, not earlier than the 28th week. A person may object to the HIV tests, but not the syphilis tests.

People of every gender and orientation can have any of these tests. If you are unsure what applies to you, ask the clinician to explain the options.

Step 4: Give your samples

Most STD tests use one of three kinds of sample. Which ones you give depends on the tests chosen.

Urine sample

You urinate into a small cup in a private restroom. Urine can be used to test for chlamydia, gonorrhea and trichomoniasis. It takes under a minute and is painless.

Swab sample

A swab is a soft cotton-tipped stick that collects cells from a body site. Depending on your exposures, a swab may be taken from the throat, rectum, vagina, cervix or the opening of the penis. Some clinics let you collect a vaginal or rectal swab yourself in private, with instructions. Others have the clinician do it.

A swab can feel a little uncomfortable, but it is quick. If something hurts, say so. You can ask to pause or to collect it yourself.

If you have a sore or blister, the clinician may swab it to test for herpes or syphilis. The Dallas County Sexual Health Clinic page notes that it does not do routine herpes blood screening, so ask a clinic about herpes testing before booking if that is what you need.

Blood sample

A blood draw from your arm is used for HIV, syphilis and hepatitis tests. A fingerstick may be used for a rapid HIV test, with a result in a short time. The Resource Center and the Dallas County clinic list rapid HIV testing. Some people feel lightheaded when blood is drawn. Eat beforehand if you are prone to this, and tell the person drawing your blood.

Step 5: Understand what a full STD panel is and is not

An "STD panel" is a bundle of tests ordered together. There is no single standard definition. One clinic's panel may differ from another's.

A typical STD panel might include:

Chlamydia
Gonorrhea
Syphilis
HIV
Sometimes trichomoniasis or hepatitis B and C

A panel does not usually include everything. The CDC does not recommend routine screening for herpes in people without symptoms. HPV testing is a separate matter. The CDC recommends cervical cancer screening for some groups, and that is ordered differently from an STD panel. The Resource Center's page lists a hepatitis A, B and C panel as a separate $100 test.

Ask the clinician exactly which infections are in your panel and from which body sites. The Dallas County clinic page lists testing for HIV, hepatitis C, syphilis, gonorrhea, chlamydia, trichomoniasis and mpox. That page also says the clinic does not do Pap smears or BV and yeast testing.

Step 6: Get your results

How long results take depends on the test and the clinic.

A rapid HIV test may give a result in a short time during the visit.
Urine, swab and blood lab tests often take a few days. Ask the clinic for its own timeline.

Ask how you will hear back before you leave. Find out whether the clinic calls, uses a portal or asks you to return. Ask whether a negative result is reported to you too, since some clinics only contact people about results that need follow-up.

Window periods

A window period is the time after an exposure before a test can reliably detect an infection. The CDC says nucleic acid tests for HIV can usually detect infection 10 to 33 days after exposure. Antigen and antibody lab tests on blood from a vein usually work 18 to 45 days after exposure. Rapid antigen and antibody tests on a fingerstick take 18 to 90 days. Antibody tests take 23 to 90 days. For other infections, ask the clinician about timing based on your exposure.

What results can mean

A negative result may mean the test did not find evidence of that infection at that time. If your exposure was recent, a clinician may suggest testing again later. A positive result means the test found evidence of an infection, and a clinician will explain the next steps.

Bacterial infections such as chlamydia, gonorrhea and syphilis, and trichomoniasis, are curable with treatment from a clinician. HIV and herpes are not curable but are treatable and manageable. Only a clinician can prescribe treatment, and your clinician will tell you what applies to you.

Texas DSHS lists chlamydia, gonorrhea, syphilis and HIV as notifiable conditions. A positive result is reported to public health, and the clinic or health department may ask about recent partners so they can be offered testing.

The CDC Legal Status of EPT in Texas page says Texas rules allow clinicians to prescribe medicine for partners of an established patient without examining the partner. Ask your clinician whether that is an option for you.

Tips for a smoother visit

Call ahead. Confirm the hours, whether you need an appointment, and what to bring. The Dallas County clinic's phone line opens at 7:45 a.m., and its hours differ by day.
Name your symptoms. Even small ones help the clinician choose the right tests.
Mention every body site involved. Throat and rectal infections are often missed when only urine is tested.
Ask about costs first. If a clinic's page does not list a price, ask when you book.
Ask about PrEP and PEP. Several Dallas clinics offer them, including the Dallas County clinic, Resource Center and Prism. Ask the clinician whether they fit your situation.
Ask about vaccines. Some clinics offer HPV vaccine, according to the CDC GetTested listings.

Common mistakes to avoid

Assuming a standard checkup includes STD testing. Tests are usually ordered only when you ask for them or the clinician suggests them.
Skipping tests at certain body sites. A urine test alone does not check the throat or rectum.
Testing too soon after an exposure. Ask the clinician whether a repeat test would be useful.
Not asking what is in the panel. Do not assume it covers every infection.
Leaving without a plan for results. Know how and when you will hear back.

If you are a teen

Texas Family Code Section 32.003 lets a minor of any age consent to diagnosis and treatment of reportable infectious diseases. That covers reportable STIs and HIV, and parent or guardian consent is not needed for that care. The same section lets a physician tell a parent or guardian about the treatment, with or without the minor's consent. A provider may, but is not required to, do so. Ask the clinic about its practice before the visit.

The Children's Health Adolescent and Young Adult Medicine clinic says a parent or guardian must give general consent for a minor to be treated there, so ask about this when you call.

Your next step

Pick one clinic from the list above and call to ask about an appointment, fees and which tests are included. The CDC's GetTested locator can help you find other free or low-cost options near your ZIP code.

Texas DSHS also lists a free mailed self-testing program for HIV, syphilis, gonorrhea and chlamydia for anyone in Texas aged 13 or older. See the DSHS page on free at-home testing for current details.
