What are the 12-markers:
| Sample | What we test for |
|---|---|
| Urine or swab (10 pathogens) | Chlamydia · Gonorrhea · Syphilis · Trichomonas · HSV-1 · HSV-2 · Mycoplasma genitalium · Mycoplasma hominis · Ureaplasma urealyticum & parvum · Gardnerella vaginalis |
| Blood | HIV-1 & HIV-2 antibody · HIV-1 p24 antigen (4th generation) |
you can test all or just the markers you need. See what each marker actually means →
The one thing most people get wrong
A urine test cannot rule out a throat or rectal infection. If your exposure was oral or anal and we only test urine, those sites were never tested at all — and pharyngeal gonorrhea is frequently silent. CDC notes that NAAT is validated for pharyngeal and rectal specimens. Tell us how you were exposed and we will collect the right sites. Which site to swab →
Why molecular, not rapid
| Rapid antigen/antibody test | Molecular PCR (what we run) | |
|---|---|---|
| What it finds | A protein marker — indirect evidence | The pathogen's own genetic sequence |
| Early / low-load infection | Frequently missed | Far more sensitive |
| Asymptomatic infection | Often missed | Detected |
| CDC position | — | NAAT is the preferred method for chlamydia and gonorrhea |
What happens if you are positive
If you are positive and treatment is clinically appropriate, a licensed physician in our partner network may see you between 5:00 and 6:00 PM the same day, or you can book for the next day. What they prescribe depends on your result — the organism, your symptoms, allergies, pregnancy status and history. We do not publish dosages, because a dosage is a prescription and a prescription requires a physician. What we do publish is the framework the physician works from: the CDC treatment pathways →
Which other STD tests can you get here in Houston?
- Trichomoniasis test: Trichomonas and Mycoplasma genitalium by PCR, two pathogens basic panels often skip.
- Ureaplasma and Mycoplasma hominis test: what a positive result can and cannot mean.
- Gardnerella / BV test: why a positive result is not an STI on its own.
- HSV PCR test: lesion swab PCR versus a blood antibody test for herpes.
- STD test after exposure: how long to wait before a test is accurate.
- STD test after a hookup: same-day, private testing.
- Same-day STD testing: standard same-day results or 2-hour STAT.
- Rapid STD test: 2-hour PCR results instead of a 15-minute strip.
FAQ
- How fast are STD results?
- Sample by 1:00 PM and your results are ready the same day at 5:00 PM. STAT results in 2 hours if we collect by 3:00 PM.
- Can I be treated the same day?
- If you are positive and treatment is clinically appropriate, a licensed physician in our partner network may see you between 5:00 and 6:00 PM that same day, or you can book for the next day.
- Do I need an appointment or insurance?
- No to both. Walk in any weekday, 9 to 5, except major holidays. Texting us first just lets us prepare the right panel and collection sites.
- Is a urine test enough?
- Not if your exposure was oral or anal. A urine-only test cannot rule out pharyngeal or rectal infection — we collect throat and rectal swabs when they are indicated.
- What does the panel cover?
- Chlamydia, gonorrhea, syphilis, trichomonas, HSV-1, HSV-2, M. genitalium, M. hominis, Ureaplasma (both species), Gardnerella, plus HIV antibody and p24 antigen.
- Is it confidential?
- Yes. Testing and treatment are private and handled under HIPAA and applicable Texas law. No referral, no appointment.
- How much does a full STD screening cost?
- We do not publish a price list, because what you need varies: the number of targets, the number of collection sites, and standard or STAT. Standard same-day testing runs up to 40% less than a typical urgent-care visit, with no facility fee and no insurance required. Text (713) 832-8892 and we will tell you the exact figure before you come in. What STD testing costs here →
- Where can I get STD tested for free in Houston?
- Free options exist. Harris County Public Health tests for HIV, syphilis, gonorrhea and chlamydia and says results take about one week, and community health centers offer free or low-cost HIV testing. Free programs usually cover fewer tests and fewer body sites. We are not free: we are the option when you want the full 12-marker PCR panel and a result today. What a free or cheap test can miss →
- Does Texas have free STD testing?
- Yes. In Texas, free or low-cost STI testing is offered mainly through local public health departments and community health centers; in the Houston area that includes Harris County Public Health. What is tested, who qualifies and how long results take vary by program.
- Does CVS do full STD testing?
- CVS MinuteClinic offers STD testing, and its own site says results for many infections, such as chlamydia and gonorrhea, are available within 1 to 2 days. “Full” means different things at different places, so ask which organisms and which body sites are covered. Our 12-marker PCR panel is run in our own lab, with results the same day at 5:00 PM.
- Where do I park?
- Parking is free in the large lot right in front of our building at 3707 Westcenter Dr, with accessible spaces near the front walk. We are Suite 100 on the ground floor.
- Are you open on holidays?
- We are closed on Saturday and Sunday, and on major holidays such as Thanksgiving, Christmas and New Year’s Day. Veterans Day is a regular workday, 9:00 AM to 5:00 PM.

Is the lab licensed, and can you check it yourself?
Yes. We run the panel in-house, in our own lab at this address. Our certificates hang on our wall: CLIA #45D2048957, a Certificate of Accreditation from CMS valid from 02/21/2026 to 02/20/2028, and CAP #8722734 from the College of American Pathologists. You can look up the CLIA number yourself on the CMS website. The laboratory director's name is blurred on this website. See the certificates and how to verify them →
