📞 Call Now for Confidential TestingRegular STD testing is an important part of personal health care for people living on the San Francisco Peninsula. Many STIs cause no symptoms—CDC estimates about 1 in 5 Americans has an STI—so screening is the only way to know your status. For sexually active adults, CDC guidance recommends routine screening for chlamydia and gonorrhea in younger adults and testing whenever you have a new partner, symptoms, or a potential exposure. In the Bay Area, population movement between San Mateo, Burlingame and Redwood City increases the importance of accessible testing and fast treatment. Early detection prevents complications, reduces transmission risk, and opens access to prompt treatment when needed. Our San Mateo centers offer confidential testing, counseling, and linkage to care. Whether you live in Downtown San Mateo, Hillsdale, Baywood-Aragon or commute via US-101, testing is quick and private. Normalizing testing reduces stigma and helps protect partners and families—getting screened is a responsible, health-focused step. If you’re unsure which tests you need, call for a private consultation to design an STI screening plan tailored to your risks and lifestyle.
