How to read these listings
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Plenty of STI clinics test for gonorrhea, chlamydia, syphilis, and HIV, then stop. Modern Concept Medical Group adds herpes, hepatitis B, hepatitis C, and TB to the same visit. Infections that go undetected precisely because they're absent from narrower panels elsewhere.
Modern Concept Medical Group prescribes and monitors PrEP: meaning the baseline HIV and kidney-function labs, the prescription, and follow-up monitoring all run through the same practice. PEP is also available, keeping both pre- and post-exposure options within one clinical relationship.
For a patient navigating PrEP adherence, a new hepatitis diagnosis, or family planning decisions, the precision of that conversation depends on the language it happens in. Modern Concept Medical Group conducts clinical care in Spanish, not through a relay, but directly with staff.

Spanish and Interpretation Built Into Every Visit
Staff here speak Spanish, and interpretation services are available for other languages, which means clinical conversations about symptoms, treatment options, and medication instructions happen with real precision, not guesswork compressed into a rushed exchange.
Title X Makes Minor Confidentiality Legally Binding
As a Title X family planning provider, Planned Parenthood Pasadena and San Gabriel Valley is federally mandated to keep services for minors legally confidential: not as a policy preference but as a structural requirement that governs how records are handled, billing is routed, and consent is documented.
PrEP, PEP, and DoxyPEP Prescribed Here Directly
Chasing down a second provider to prescribe PrEP or DoxyPEP after an STI visit adds weeks of unprotected exposure. Planned Parenthood Pasadena and San Gabriel Valley prescribes PrEP, PEP, and DoxyPEP in-house, so prevention medication is initiated at the same clinic that manages testing and 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.

Los Angeles County HIV care continuum (2023)
Los Angeles County recorded 19.6 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Los Angeles County residents living with HIV, 91.6% know their status · 72.8% are in care · 65.2% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Los Angeles County tests for syphilis.

Fair Oaks Avenue cuts through a city that feels unhurried, with the Rialto Theater anchoring a small-town streetscape and bungalows shading quiet blocks in Oak Knoll and Madison Heights. But that composed surface sits on a practical tension: more than half of South Pasadena households rent, and at roughly $1,800 a month, rent here runs high enough that an unexpected out-of-pocket medical bill lands differently than it would somewhere cheaper.
That cost pressure matters most for young adults in their late teens and twenties, the years when STI rates climb and relationships shift most often. Los Angeles County STI figures on this page make clear how active transmission is in the surrounding region, and South Pasadena's share of residents in those peak years is real enough to be worth taking seriously. Most adults here are working, which means weekday clinic hours compete directly with job schedules, and the options listed on this page are not all a short walk up Huntington Drive; several require a drive out of the city, worth knowing before you plan.
For a renter in Newton Park or near the Arroyo Seco Parkway corridor, where disposable income absorbs a large rent before anything else, the fee structure matters. Several listings on this page offer sliding-scale or no-cost visits, a detail that shifts the calculus considerably for someone whose household budget is already committed to keeping a South Pasadena address.

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.
