STI testing is a medical process used to check for sexually transmitted infections, such as chlamydia, gonorrhea, and HIV. It typically involves providing a urine sample, a blood test, or a swab from the genital area. Regular testing is important for sexually active individuals, as many STIs can be asymptomatic, meaning they show no symptoms. Getting tested is a straightforward and confidential procedure that can be done at clinics, hospitals, or through at-home testing kits. Early detection of STIs can lead to effective treatment and help prevent the spread of infections to others.
