Houston sprawls across three counties and has more walk-in lab locations than almost any metro in the country, so rapid STD testing in Houston is mostly a question of picking the closest site. Below: the private walk-in route with every address and hours, the city’s sliding-scale clinics, and where urgent care fits.

The fastest option: order online, walk into a lab today

Private lab draw sites cover the whole metro: the Texas Medical Center and Museum District, Montrose and Midtown, the Galleria and Memorial, Katy and Cypress to the west, Sugar Land and Missouri City to the southwest, Pearland and Clear Lake to the south, Pasadena and Baytown to the east, and Humble, Spring, and The Woodlands to the north. Order online, walk in with no appointment, spend about 5 minutes, and get results in 1 to 2 days in a private account. Nothing is billed to insurance and nothing goes on your medical record.

Most sites open at 7 or 8 a.m. on weekdays and many open Saturday mornings. The full list with hours is below.

Houston Health Department health centers

The City of Houston provides STD testing and treatment on a sliding fee scale at several health centers. Services are by appointment; call 832-393-5427 to schedule.

  • Northside Health Center: 8504 Schuller Rd, Houston, TX 77093 (832-395-9100)
  • Sharpstown Health Services: 6201 Bonhomme Rd, Houston, TX 77036 (832-395-9800)
  • Sunnyside Health and Multi-Service Center: 4506 Wilmington St, Houston, TX 77051 (832-395-0206)
  • La Nueva Casa de Amigos Health Center: 1809 N. Main St, Houston, TX 77009 (832-395-0570), which also offers PrEP and PEP

Tests include chlamydia, gonorrhea, syphilis, hepatitis, herpes (when symptoms are present), and rapid and conventional HIV. The department does not deny services because of inability to pay. Rapid HIV results are available during the visit; other results take several days. Harris County Public Health serves the unincorporated county with similar clinics; check its site for locations.

Urgent care in Houston

Urgent care chains are everywhere in Houston, and most offer STD testing with an exam. Without insurance, plan on a visit fee of $100 to $200 plus lab charges, with results in 2 to 5 days. Some run rapid HIV on site. Best when you have symptoms and want treatment today.

Texas notes

  • Expedited partner therapy is allowed in Texas: a clinician can treat your partner for chlamydia or gonorrhea without a separate visit.
  • Minors can consent to their own STD testing and treatment in Texas.
  • Syphilis and congenital syphilis have risen sharply in Harris County; include syphilis in any panel and test during pregnancy.

When to test

Chlamydia and gonorrhea at 2 weeks after exposure, HIV and syphilis at 6 weeks, herpes antibody at 12 weeks. With symptoms, test now and retest after the window.

Which tests to order

The 10-test panel ($139) covers HIV, syphilis, chlamydia, gonorrhea, herpes 1 and 2, and hepatitis A, B, and C in one visit. After one known exposure, chlamydia and gonorrhea together ($99) at two weeks and HIV plus syphilis ($49 each) at six weeks is a reasonable minimum.
