Herpes and Hepatitis C Tested Here, Same Visit
Leaving herpes or hepatitis C undetected means a second appointment somewhere else, another copay, and more time before care begins. At Golden Valley Health Centers, herpes and hepatitis C testing sit alongside the core bacterial panel. One visit closes the gap that a shorter panel leaves open.
Spanish-Language Care Without the Extra Step
When STI care requires a workaround for language, the workaround itself becomes a barrier: questions go unasked, nuance gets lost, and follow-through suffers. Golden Valley Health Centers delivers care in Spanish directly, so the clinical conversation carries its full weight from the first exchange.
Beyond the dedicated testing centers above: at-home kits by mail, hospital labs certified for STI testing, local clinicians who can order a panel during a regular visit, pharmacies for self-test kits and prescriptions, and online PrEP & treatment.

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.

Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when

Confidentiality & consent in CaliforniaMinor consent and partner treatment (EPT) under state law, plus how to test privately
Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
Can a minor consent on their own?
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
