Sexually transmitted infections (STIs), also called sexually transmitted diseases (STDs), are incredibly common. With over 20 million new STI cases in the U.S. each year, getting tested regularly is one of the most important things you can do to maintain your sexual health and avoid spreading infections to partners.
Testing for STIs can seem daunting, but understanding how STI testing works and what to expect during the process can help you feel more comfortable. Here’s a look at what you need to know.
How does STI testing work?
STI testing checks for infections transmitted through sexual contact, including through vaginal, oral and anal sex. Testing typically involves collecting a sample that will be analyzed for pathogens that cause STIs.
Samples may include urine, blood, throat or genital swabs, or discharge from sores. In some cases, a physical exam may be necessary for a diagnosis.
You can access STI testing through a healthcare provider’s office, local healthcare clinics like Planned Parenthood, or patient service centers like those run by Labcorp.
What is typically included in STI screening?
Comprehensive STI screenings typically include testing for the most common infections, which according to the World Health Organization, include syphilis, gonorrhea, chlamydia and trichomoniasis. Any specific concerns and symptoms should be discussed with your healthcare provider. They can help determine the right test for you.
Labcorp OnDemand’s Standard STI Test screens for syphilis, gonorrhea, chlamydia and HIV. Our Complete STI Test screens for syphilis, gonorrhea, chlamydia, trichomoniasis, HIV, hepatitis B and hepatitis C. While hepatitis C is not technically an STI, it is a bloodborne pathogen that can be transmitted during sexual activity.
How do I prepare for my STI test?
To get the most accurate results, it’s important to properly prepare for your STI test. Preparation may include:
- Not urinating for 1-2 hours prior for a urine sample
- Not douching for 24 hours prior for a vaginal swab
- Not having oral sex for 24 hours prior for a throat swab
- Abstaining from vaginal sex for 24-48 hours prior to testing for trichomoniasis
It’s also recommended you avoid biotin supplements (commonly found in products promoting hair, skin and nail health) for at least 72 hours before providing a blood sample for an STI test, as biotin can interfere with lab results.
Preparation can vary depending on the type of sample required, so talk to your healthcare provider if you have any questions about how to prepare.
What do my STI test results mean?
Once your sample is analyzed, you’ll receive your test results, typically within a few days. When purchasing Labcorp OnDemand tests, it’s important to discuss your test results with your healthcare provider to determine your next steps.
Depending on your results, you may need to start treatment or notify recent partners about potential exposure.
"Communicating with partners about STI testing is so important for everyone's health and peace of mind," says Irene Cheung, family nurse practitioner and clinical lead for Labcorp OnDemand. "Have an open conversation about your results and encourage your partners to get tested as well."
Getting tested is the best way to understand your exposure to STIs. Prioritize your sexual health by making STI testing a routine part of your healthcare.
