Is STI Testing a Blood Test or Urine Test?

STI testing can involve a blood test, urine test, or swab, depending on which sexually transmitted infection is being checked for. Urine samples are commonly used to test for chlamydia and gonorrhea, while blood tests can screen for infections such as HIV and syphilis. Knowing which test you may need can help you feel more prepared and understand what to expect during your visit. AFC Urgent Care Attleboro offers STI testing for patients in Attleboro, North Attleboro, Plainville, and nearby Massachusetts communities. We are open seven days a week from 8 AM to 8 PM, with walk in care available.

Is STI Testing Done With Blood or Urine?

STI testing may use blood, urine, or a swab, depending on the infection and your individual circumstances. There is no single test that checks for every sexually transmitted infection, so your provider will recommend the appropriate screening based on your symptoms and potential exposure.

Common testing methods include:

  • Urine tests: Often used to detect chlamydia and gonorrhea. You may be asked to provide a urine sample in a collection cup.
  • Blood tests: Commonly used to screen for HIV, syphilis, and certain forms of hepatitis.
  • Swab tests: May be used to collect samples from the throat, rectum, genital area, or a sore when appropriate.

Your provider can explain which sample is needed and whether you should follow any preparation instructions before testing.

Which STIs Can a Urine Test Detect?

A urine test is commonly used to screen for chlamydia and gonorrhea, two bacterial infections that can affect the genital tract. These infections may cause unusual discharge, burning during urination, or pelvic discomfort, but many people have no noticeable symptoms.

A urine test does not detect every STI. If you are concerned about HIV, syphilis, or another infection, your provider may recommend a blood test or a different type of sample. The appropriate testing plan also depends on the type of sexual contact you have had, since an infection affecting the throat or rectum may require a sample from that area.

At AFC Urgent Care Attleboro, our team can discuss your concerns and help determine which available tests are appropriate for your needs.

How Do You Prepare for STI Testing at Urgent Care?

Preparing for an STI test is usually straightforward, but the steps can vary based on the type of sample needed. Before your visit, consider these tips:

  • Share relevant details: Tell your provider about any symptoms, possible exposure, and concerns about specific infections.
  • Ask about preparation: Some urine tests may require you to avoid urinating for a period before sample collection. Follow the instructions provided by your clinic.
  • Discuss timing: If exposure was recent, ask whether testing now or repeating a test later is appropriate.
  • Ask about results: Find out how results will be communicated and what follow up care may be needed.

You do not need to wait until symptoms appear to ask about testing. If you have a known exposure or concerning symptoms, seek medical advice promptly.
