What Does an STI Test Involve?

Getting tested for sexually transmitted infections (STIs) can sound very intimidating, but in reality, it's a straightforward process that can save you from a lot of stress in the long run. Whether you're experiencing symptoms, have a new partner, or just want to stay on top of your sexual health, STI testing is a responsible way to make sure everything is in check.


So, what does an STI test actually involve? Let’s break it down and take the mystery (and unnecessary fear) out of the process.


Step 1: The Conversation

Before any actual testing happens, your healthcare provider will likely ask you a few questions about your sexual history. Our intake screening at Trusti is similar. These conversations aren’t supposed to feel like an interrogation; they’re just trying to determine which tests make the most sense for you. You might be asked about:


  • Your sexual partners (past and present)

  • The types of protection you use (condoms, dental dams, etc.)

  • Any symptoms you may have noticed

  • Your general health and medical history


Honesty is key here—healthcare professionals aren’t there to judge you, just to help keep you healthy. And if you get stuck with an insensitive practitioner (trust us, we’ve been there), just know that you are doing the right thing.


Step 2: The Actual Tests

Depending on what STIs you’re getting tested for, the process may involve one or more of the following:


  • Urine Sample – If you’ve ever peed in a cup at a doctor’s office, congratulations, you’ve already mastered this part. Urine tests are commonly used to detect infections like chlamydia and gonorrhea.

  • Blood Test – A small blood sample can be taken from a vein (usually in your arm) or, in some cases, a finger prick. Blood tests are used to check for HIV, syphilis, and hepatitis B or C.

  • Swab Test – This involves using a cotton swab to collect a sample from areas like the throat, genitals, or rectum. Swabs are often used to test for gonorrhea, chlamydia, and HPV.

  • Physical Exam – Some STIs, like genital warts or herpes, may require a visual examination. A healthcare provider will check for sores, rashes, or other signs of infection. They don't judge what you have going on down there, as they literally see hundreds of genitalia every single day.


These tests don’t take long, and while some might be slightly uncomfortable (we’re looking at you, swabs), none should be painful.


Step 3: The Waiting Game

After the tests are done, the next step is waiting for the results. The timeline can vary:


  • Rapid HIV tests can give results in 1-20 minutes.

  • Other blood and urine tests take up to two weeks to come back from a lab.

  • Certain swab tests might take a bit longer depending on the lab processing time.


The experts at the clinic will always communicate how long you have to wait until you get your results. If any of your results come back positive, don’t panic. Many STIs are easily treatable, and for those that aren’t curable, there are effective treatments to help manage them.


Who Should Get Tested, and How Often?

According to the CDC, PHAC, and PHO, STI testing isn’t just for people who think they have symptoms. In fact, many infections don’t show symptoms at all. Here are some general guidelines:

  • If you’re sexually active: Regular testing is recommended, especially if you have multiple partners.

  • If you’re under 25: The CDC and PHAC suggest annual chlamydia and gonorrhea testing for sexually active people under 25.

  • If you’re pregnant: STI testing is often part of prenatal care to protect both you and your baby.

  • If you’ve had unprotected sex: Even if you feel fine, it’s a good idea to get tested just in case.

  • If you have a new partner: A quick check-up can give both of you peace of mind.


The Bottom Line

STI testing is a simple and responsible way to take care of your health. Whether it’s a urine sample, blood test, or swab, the process is usually quick and painless. Plus, with modern medicine, most STIs are manageable, and early detection can prevent complications down the road.


So, if it’s been a while since your last test, consider making an appointment. Your future self (and your partners) will thank you!
