Many sexually transmitted infections are asymptomatic; the CDC estimates roughly 1 in 5 people in the U.S. has an STI at any given time. Routine screening helps detect infections early, prevents complications like infertility or liver disease, and reduces transmission to partners. The CDC recommends yearly testing for sexually active adults with new or multiple partners, and more frequent screening for higher-risk individuals. In Altadena, where residents commute to Pasadena and Los Angeles and engage in active social communities, timely testing is practical and protective. Our confidential STI screening services normalize testing, reduce stigma, and provide clear next steps—treatment, vaccination referrals, and partner notification assistance. If you’re sexually active, have a new partner, or experience symptoms, schedule a private STD test in Altadena to stay informed and healthy.
