STD Testing in California

Getting tested for STDs in California can help you identify STDs early, protect yourself and your partners, and limit the spread of STDs – especially STDs with undetectable or mild symptoms.

STDs are a national concern, and California has an especially high rate of syphilis, ranking seventh in the country according to the most recent data from the Centers for Disease Control and Prevention (CDC). Additionally, the state is ranked sixth for congenital syphilis, 32nd for chlamydia, and 25th for gonorrhea.

Many STDs are curable. For those that aren’t, treatments are usually available to help manage symptoms and prevent you from passing them onto others. If you’re sexually active, regular testing is the only way you can know for sure if you have an STD and get the treatment you need to prevent potentially serious health issues and stop the spread.

There are numerous California STD testing resources where you can get answers to your questions about STDs and get tested, often for free or at a low cost. AHF offers free testing, and Planned Parenthood offers a full suite of sexual health services, along with interpreters if you let them know in advance.
