Planned Parenthood Mar Monte in Merced tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee with Medicaid and insurance accepted; bacterial infections treated same visit, and an appointment is required.
Planned Parenthood Mar Monte in Merced offers care in Spanish and interpretation services for other languages, which means nuanced conversations about prevention, PrEP timing, or treatment decisions happen without a layer of approximation between a patient and their provider.
Title X designation gives Planned Parenthood Mar Monte in Merced a concrete legal obligation: services for minors are confidential by federal program rules, not just clinic policy: meaning a young person's testing, treatment, or family planning care cannot be disclosed without their consent.
Without an on-site prescriber for PrEP or PEP, a person in Merced faces a second appointment at a separate practice. Days lost and prevention interrupted. Planned Parenthood Mar Monte carries both, with PrEP available for uninsured patients, so prevention doesn't stall between referral and prescription.

STD stats & rates
How reported STI rates in Merced County, the county that includes Tuttle, compare with California and U.S. averages, based on the most recent 2023 surveillance data.
#11 of 58 California counties for chlamydia, a higher rate than 81% of the state
| Infection | Merced County | California | United States |
|---|---|---|---|
| Chlamydia | 498.1 1,454 cases ▲ 1% | 491.1 | 492.2 |
| Gonorrhea | 108.2 316 cases ▼ 43% | 190.2 | 179.5 |
| Syphilis (P&S) | 14.4 42 cases ▼ 12% | 16.3 | 15.8 |
| Syphilis (early) | 11.3 33 cases ▼ 41% | 19.1 | 16 |
| Syphilis (late/unknown) | 76.4 223 cases ▲ 64% | 46.7 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Merced County, chlamydia has risen from 461.2 to 498.1 per 100,000 (8%), gonorrhea has fallen from 236.5 to 108.2 per 100,000 (54%), and P&S syphilis has fallen from 21 to 14.4 per 100,000 (31%).

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 Merced County.
Local HIV snapshot
Merced County HIV care continuum (2023)
Merced County recorded 22.6 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Merced County residents living with HIV, 81% are in care · 72.9% 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 Merced County tests for syphilis.

Data & references
Local context
Tuttle sits where the valley floor opens toward the Sierra foothills, a place where seasons turn visibly and work rhythms shape the calendar. For young adults moving through their twenties and thirties (whether settling in, passing through, or building roots here) STI testing fits naturally into the habits of staying healthy, much like a regular checkup or dental visit. The screening itself takes little time and carries no judgment; it's simply part of knowing your status. Testing in and around Tuttle is listed on this page through clinics and providers within reach.
Because confidentiality matters in a town where faces repeat and word travels, these services keep results private by design, not as an afterthought. You choose when to test, and the outcome stays yours alone. Routine screening catches what has no symptoms and prevents what spreads silently. Whether you're new to the area, in a new relationship, or simply keeping a regular rhythm of self-care, the testing available in and around Tuttle gives you the facts you need without the friction of distance or disclosure.
Getting there
Tuttle scores 12.34/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
