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.

Herpes testing is different from most other STI testing. The right test depends on whether you have a sore right now, and the wrong test at the wrong time can be confusing.

This guide walks you through how to get a herpes test in Dallas, step by step. It explains the two main test types, what the CDC says about each, and what to ask a clinician. It also covers how to talk with a partner afterward.

The short version

There are two main ways to test for herpes. A swab of a sore looks for the virus itself. A blood test looks for antibodies your body made in response to the virus.

The CDC STI Treatment Guidelines (2021) favor testing a sore with a swab when one is present. They do not recommend routine herpes blood screening for people with no symptoms. The reasons are covered below.

What you need before you start

You do not need special supplies. A little preparation makes the visit go more smoothly.

A note of what you have noticed. Write down where, when it started and what it looked or felt like. Tingling, burning, small bumps, blisters or open sores are all things clinicians ask about.
A plan for timing. If a sore is present, getting seen soon matters. More on that in Step 2.
A list of your questions. Examples: which test is right for me, what will the results show, and what happens if they are positive.
Insurance information, if you have it. Several Dallas clinics also use sliding scale fees, covered later.
A phone. Some Dallas clinics ask you to call or book an appointment first.

Step 1: Know what herpes symptoms can look like

Herpes symptoms vary a lot. The CDC says many people with genital herpes have very mild symptoms or none at all, so a person may not know they have it.

When symptoms do appear, the CDC describes them as one or more blisters or sores on or around the genitals, rectum or mouth. Some people notice itching, tingling or pain before a sore appears. The first outbreak can also come with fever, body aches or swollen glands, according to the CDC.

Other conditions can look similar. Ingrown hairs, razor irritation, yeast infections and other STIs can cause bumps or sores. Only a clinician or a test can say what is causing them. Looking at a photo online is not a reliable way to tell.

Step 2: If you have a sore, get seen while it is there

This is the step people most often miss. A swab test works best on a fresh sore, because the virus is easiest to find early.

The CDC STI Treatment Guidelines (2021) say that a lab test on a swab from a sore (a nucleic acid amplification test, often called PCR) is the preferred way to confirm genital herpes. The CDC notes that a swab can come back negative even when herpes is the cause, especially if the sore has started to heal.

If you notice a sore, it helps to call a clinic that day and tell them you have a new sore. Do not wait for it to go away first. If a swab is done and the result is negative, ask the clinician what that does and does not rule out.

Step 3: Understand the blood test, and why it is not routine

A herpes blood test looks for antibodies. The CDC recommends that when blood tests are used, they be type-specific, meaning they can tell HSV-1 antibodies from HSV-2 antibodies.

The CDC STI Treatment Guidelines (2021) say that antibodies can take time to build. The guidelines describe that it can take up to 12 weeks after infection for a blood test to detect them. A test taken very soon after a possible exposure can miss an infection.

The CDC also does not recommend routine herpes screening of people without symptoms in the general population. Its reasoning includes these points:

A blood test cannot show when the infection happened or which body site it affects.
Results near the cutoff can be falsely positive, so a clinician may suggest a second test to confirm.
Many people who test positive have no symptoms, and the CDC notes that screening has not been shown to reduce spread or improve health in the general population.

The CDC does say blood tests can be useful in specific situations. These include recurring or unusual symptoms with a negative swab, a partner who has been diagnosed with genital herpes, or a person who simply wants to talk through their situation with a clinician. If you are wondering whether a blood test makes sense for you, ask a clinician. Asking is reasonable, and the clinician can tell you what the result would and would not show.

Step 4: Know the difference between HSV-1 and HSV-2

Two viruses cause herpes. Both can cause infections in the mouth or the genital area.

HSV-1 is most often associated with oral herpes (cold sores or fever blisters), but the CDC notes it can also cause genital herpes, often through oral sex.
HSV-2 is most often associated with genital herpes, according to the CDC.

This matters for reading a test. A type-specific blood test can tell you which virus your body has antibodies to. It cannot tell you where on your body the virus lives. A positive HSV-1 blood result, for example, could reflect a past cold sore and not a genital infection. A swab of a genital sore can tell you which type is present in that sore.

Both types are common. Neither says anything about your character or your choices.

Step 5: Book a herpes test in Dallas

Dallas has several places to ask about herpes testing. Which one fits depends on whether you have a sore and what you want to ask. Before you go, call and ask whether they can swab a sore, whether they offer type-specific blood testing, and what it costs. Not every clinic publishes its herpes services, so a quick call saves a trip.

Dallas County Health and Human Services Sexual Health Clinic. It is at 2377 N. Stemmons Freeway, 1st Floor, Suite 100, Dallas, TX 75207, phone (214) 819-1819. The county's page lists treatment for genital herpes outbreaks. The same page says the clinic does not do routine herpes blood screening, which matches the CDC's approach. Appointments are required, and the county says same-day or next-day appointments are offered. The phone line opens at 7:45 a.m. Clinic hours are Monday, Tuesday, Thursday and Friday 8:00 a.m. to 4:00 p.m., and Wednesday 10:00 a.m. to 6:00 p.m. The county page lists no fees, and the CDC GetTested listing says to contact the organization about eligibility. The county page also says people who want routine testing without symptoms are directed to the DCHHS Mobile Medical Unit.

Prism Health North Texas. Its Oak Lawn Health Center is at 2801 Lemmon Ave, Suite 200, Dallas, TX 75204, phone 214-521-5191. Prism says it uses sliding fee rates based on household income and size, accepts Medicaid, Medicare, CHIP and most private insurance, and does not deny care based on ability to pay. Prism says appointments should be scheduled in advance, with same-day and walk-in appointments for urgent issues depending on availability.

Resource Center Health. The Nelson-Tebedo clinic is at 2603 Inwood Rd., Dallas, TX 75235, phone 214.528.2336. Its testing page lists prices for specific tests such as gonorrhea and chlamydia, and does not list a herpes test or price. Call to ask.

Community health centers. The CDC GetTested listings show sliding scale options at Foremost Family Health Centers (Martin Luther King Jr Family Clinic, 2922-B MLK Jr Blvd, (214) 426-3645), Parkland Health's Southeast Dallas Health Center (9202 Elam Rd, (214) 266-1600), AIDS Healthcare Foundation (7777 Forest Ln Ste B 122, (972) 383-1060) and Neighborhood Medical Center (5917 Belt Line Rd, (972) 726-6464). The listings do not say whether each clinic offers herpes swabs or blood tests, so ask when you call. For a full list with details, see the Dallas clinic list.

A note for teens: Texas Family Code Sec. 32.003 says a minor of any age may consent to diagnosis and treatment of a reportable infectious or communicable disease, and parent consent is not required for that care. The same law allows a physician to tell a parent or guardian about the treatment. A clinic can explain how it handles this, so it is fair to ask before your visit.

Step 6: At the visit

Expect the clinician to ask about symptoms, any partners who have had symptoms, and what you are hoping to learn. These questions are routine and are not a judgment.

If you have a sore, the clinician may gently swab it. It can be uncomfortable for a moment. If you and the clinician decide on a blood test, it is a standard blood draw.

You can also ask about testing for other infections at the same visit. Some are tested by urine or blood instead of a swab. If you want to learn about another common one, read about chlamydia symptoms, testing and treatment in Dallas.

Step 7: Read your results with a clinician

Results are best understood with someone who knows your history. These are general patterns, and a clinician can tell you what applies to you.

A positive swab. A positive swab from a sore generally means the virus was found in that sore. The clinician can tell you which type it was.
A negative swab. This may mean the virus was not found in the sample. The CDC notes swabs can miss the virus, especially in healing sores, so ask whether a repeat swab or a blood test makes sense.
A positive blood test. This may mean your body has made antibodies to HSV-1 or HSV-2. It usually cannot say when the infection happened or where on the body it is. Results close to the cutoff may need a second test.
A negative blood test. This may mean no antibodies were found. If the test was done within about 12 weeks of a possible exposure, the CDC says it could be too early to show, so a clinician may suggest testing again later.

Step 8: Plan for care and outbreaks with a clinician

Herpes is not curable, but it is treatable and manageable, according to the CDC. Many people have outbreaks that become less frequent and milder over time.

Clinicians can prescribe antiviral medicine. The CDC describes two general approaches: treatment during an outbreak, and daily suppressive therapy for people who have frequent outbreaks or want to lower the chance of passing the virus to a partner. Which approach fits depends on the person, so the choice and the details come from a clinician. Do not use leftover or borrowed medicine.

It can help to ask your clinician:

What should I do when I feel the first signs of an outbreak?
Would daily suppressive therapy make sense for me?
How can I lower the chance of passing herpes to a partner?
Is there anything to think about during pregnancy?

The CDC notes that herpes can spread even when no sore is visible, and that condoms and suppressive therapy can lower, but not remove, the chance of passing it on.

Step 9: Talking with partners

Telling a partner can feel daunting. Many people find it helps to treat it as a health conversation, not a confession.

Choose a calm, private moment, not in the middle of intimacy.
Lead with facts. You can say that herpes is common, manageable, and that you want to share information so you can both make choices.
Offer resources. The CDC has plain-language pages on genital herpes that a partner can read.
Let them react. Questions or silence are normal. Give them time.

Texas does not have an HIV-specific or STD-specific criminal exposure law, according to the CDC's 2023 analysis. If you have questions about how the law applies to your situation, an attorney can answer them. A clinic can also help you plan the conversation.

Partners may want their own testing and a talk with a clinician. Texas also has rules that let clinicians prescribe certain STD medicines for the partners of an established patient, according to the CDC's legal status page for Texas. Ask your clinician whether that applies.

Tips and common mistakes to avoid

Waiting for a sore to heal before getting seen. This is the most common mistake. A swab works best on a fresh sore.
Testing too soon after a possible exposure. A blood test may not show antibodies yet, per the CDC's window of up to 12 weeks.
Treating a blood test as a full STI check. A herpes blood test only looks for herpes. Ask separately about other infections.
Assuming a mouth result means a genital infection. A type-specific blood test cannot say where the virus is.
Assuming a standard STI panel included herpes. Many do not. Ask directly.
Relying on a mailed kit for herpes. The Texas Department of State Health Services lists its free at-home program as covering HIV, syphilis, gonorrhea and chlamydia. Herpes is not on that list.
Trying to self-diagnose from photos. Many conditions look alike.

What to expect after a herpes test

Whatever the result, a clinician can walk you through what it may mean and what comes next. For many people, a positive result is followed by a plan for outbreaks and a conversation about partners. For others, a negative result leads to a plan to retest at the right time or to look at other possible causes.

If you are worried or unsure where to begin, call the Dallas County Sexual Health Clinic at (214) 819-1819, or any of the clinics above, and say what you have noticed. They can tell you the best next step.
