STIs — also called sexually transmitted diseases (STDs) — are very common. They often do not cause any symptoms. And many people have an STI and never know it.

That’s why it's a good idea to think about getting tested if you've had oral, vaginal, or anal sex. Getting tested can put your mind at ease or alert you (and your partners) to needed treatment.

There are many common STIs, and we recommend routine testing for some of them. The Check is here to help you figure out if you should get tested for three dangerous STIs — chlamydia, gonorrhea, or HIV.

Take a few minutes to answer these simple questions. There are no right or wrong answers.

After you answer the questions, The Check will suggest which of these STI tests may be right for you. Remember — no quiz can replace the advice of your health care provider. After completing this anonymous quiz, discuss the results and any questions you have with your provider and decide together which tests are right for you.

Have symptoms? Skip The Check.

  • Sometimes there is no question that someone needs testing. Skip taking The Check and make an appointment for testing if you have any symptoms of an STI.
  • Some common symptoms include burning during urination, discharge from the penis or vagina, itching, sores on the genitals, vaginal bleeding or pain with vaginal sex, pain in the lower abdomen, or pain in the testicles.
  • You should also get tested if you are pregnant or if you have a sex partner who has been diagnosed with an STI in the past year.
