A Walk-in Clinic Offering Same-Day STD Testing in Southeast Texas

Over half of Americans will contract an STD in their lifetimes, so staying on top of your sexual health is essential. Affinity Urgent Care provides comprehensive sexually transmitted disease (STD) and STI testing with same-day results for patients in Southeast Texas—no appointment necessary. We are open daily during extended hours and have brief wait times to fit your busy schedule.

Safe & Confidential STI Screening

Depending on your sexual lifestyle, you should be tested every 3-6 months or once a year with one partner. However, if you are showing symptoms, we can diagnose and treat you. Our urgent care clinic is a non-judgmental environment where we will ask about your symptoms and listen to your concerns. We will then proceed with screening for various STIs and STDs, including the following:

  • Gonorrhea  
  • Syphilis  
  • Chlamydia  
  • Trichomoniasis  
  • Gonorrhea  
  • Human immunodeficiency virus (HIV)  
  • Genital herpes

Affinity Urgent Care performs same-day STD testing at our on-site lab, offering fast and effective treatment for responsible and safe sexual health. If your test comes back positive, our medical professionals can provide you with a treatment plan to address your condition. We offer the following tests at our clinic:

Xpert® CT/NG

Xpert® CT/NG is a PCR test that detects Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in both men and women. This STI screening tool allows for on-demand testing, providing accurate results in under an hour and respiratory test results in as little as 30 minutes.

Xpert® Xpress MVP Testing

Different infections may cause vaginitis, making diagnosis and treatment challenging. Affinity Urgent Care offers the Xpert® Xpress MVP test, an accurate PCR test that aids in diagnosing and treating vaginal infections. This test can detect:

  • Vulvovaginal candidiasis (VVC)
  • Trichomoniasis (TV)
  • Bacterial vaginosis (BV)

MVP testing provides results within an hour. This test also detects potential co-infections that may be delaying symptom resolution.

Xpert® TV

This test facilitates the fast and accurate diagnosis of Trichomoniasis in 90 minutes or less. It gives us information to provide you with the correct treatment plan for your condition.

DPP® HIV-Syphilis Rapid Test

The DPP® HIV-Syphilis rapid test is an FDA-approved dual test for both HIV and Treponema pallidum (syphilis). It provides reliable test results within 15 minutes.

"We have a special needs daughter who needed her foot looked at. Thankful that Affinity accepted her Medicaid first of all. Staff was nice, did not have a long wait, doctor was knowledgeable and understanding with our daughter, which means a lot. She was able to get x-rays done on her foot and received the results before we left. A great place to go on short notice."
"Facility was very clean. Very short wait. The doctor and x-ray tech were great!!"
"Fast and friendly. Was in and out in about an hour, and the PA and nurses were great. Much better experience than the ER."
"The Affinity care clinic in Galveston was wonderful. I walked in Memorial Day (without an appointment) and was seen by a very courteous and helpful staff. I highly recommend them."
"My experience at this urgent care facility was a pleasant one. I brought my daughter in due to an allergic reaction. The staff members there were awesome!"
