A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Tests offered
MACT Health Board in San Andreas covers gonorrhea, chlamydia, syphilis, HIV, hepatitis C, and TB on a sliding-scale fee accepted alongside Medicaid, Medicare, and private insurance. Appointments are required, bacterial infections treated same visit, and vaccines for HPV, hepatitis A, and hepatitis B are available.
Standalone STI clinics rarely hold a substance-use treatment program, those referrals typically go somewhere else entirely. At MACT Health Board, both services live within the same organization, so a visit that starts with a syphilis test can also open a door to addiction care without routing you to a separate provider.
The four-infection panel (HIV, syphilis, gonorrhea, chlamydia) is where many clinics stop. MACT Health Board extends testing to hepatitis C as well, and with on-site hepatitis A and B vaccination available, the full picture of hepatitis exposure and prevention is handled in a single setting.

How reported STI rates in Calaveras County, the county that includes Mountain Ranch, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~11% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.

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.
Between 2020 and 2023 in Calaveras County, chlamydia has risen from 17.7 to 100.9 per 100,000 (470%), gonorrhea has fallen from 66.2 to 30.1 per 100,000 (55%), and P&S syphilis has risen from 2.2 to 4.3 per 100,000 (95%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Calaveras County.
Local HIV snapshot
Calaveras County HIV care continuum (2022)
Calaveras County recorded 0 new HIV diagnoses per 100,000 (2022), against 14.9 statewide and 13.7 nationally. Among Calaveras County residents living with HIV, 77.6% are in care · 57.1% 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.
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 Calaveras County tests for syphilis.

Data & references
Local context
Mountain Ranch's Mountain Ranch Road corridor is home to a largely settled, homeowning community: more than seven in ten residents own their homes, and roughly half of households are married couples. That kind of stability shapes the rhythm of daily life here, but it doesn't erase the challenge of fitting a health appointment around a schedule already stretched thin. With labor-force participation well below the state norm and unemployment running high, many residents are either working unpredictable hours or navigating real financial pressure, and at a rent level that leaves little room for unexpected out-of-pocket costs, anything with an upfront fee can genuinely give someone pause. It means getting to a clinic involves planning a trip, not stepping out the door.
That reality lands differently for the younger adults in Mountain Ranch, people in their late twenties who are still building routines and relationships, for whom a complicated journey is often reason enough to delay. That's exactly where the range of options listed on this page earns its keep. Some offer sliding-scale fees that ease the cost calculation; others carry evening or weekend availability. For someone living off Mountain Ranch Road, having that spread of choices (across hours, distance, and price) means the right fit is actually findable.
Getting there
At 4.31/20 on the EPA walkability index, day-to-day errands in Mountain Ranch generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
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.
