STI testing can check for chlamydia, gonorrhea, herpes, HIV, and other conditions. Testing is based on a blood or urine sample or a swab. People can have a test in a doctor’s office, clinic, or, in some cases, at home.
Sexually transmitted infections (STIs) primarily transmit through sexual contact. A person can contract them through anal, vaginal, oral, or manual sexual intercourse.
STI testing can help a person find out if they have an infection. Many infections require treatment to either cure the infection or help prevent the condition from worsening or recurring.
