LivingWell Medical Clinic in Grass Valley tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis C. All at no charge, with same-visit treatment for bacterial infections. An appointment is required, and sliding-scale fees apply when donations are accepted.
Sliding-scale fees are the norm at most STI clinics, a floor that still asks something of everyone who walks in. LivingWell Medical Clinic in Grass Valley charges nothing at all: testing, treatment, and the visit itself are provided without cost, and donations are accepted only when a patient chooses to give.
Many clinics leave non-English speakers navigating care in a language that isn't their own, with no support built into the appointment. LivingWell Medical Clinic in Grass Valley has interpretation services integrated into its care, so the conversation between provider and patient can happen in the language a person actually uses.
Leaving herpes or hepatitis C off a panel means a second appointment, a separate lab, and the window where an undetected infection goes unaddressed. LivingWell Medical Clinic in Grass Valley tests for both alongside HIV, syphilis, gonorrhea, and chlamydia, closing that gap before it opens.

STD stats & rates
How reported STI rates in Nevada County, the county that includes Grass Valley, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~21% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#49 of 58 California counties for chlamydia, a higher rate than 16% of the state
| Infection | Nevada County | California | United States |
|---|---|---|---|
| Chlamydia | 170.5 174 cases ▼ 65% | 491.1 | 492.2 |
| Gonorrhea | 71.5 73 cases ▼ 62% | 190.2 | 179.5 |

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 Nevada County, chlamydia has fallen from 192.7 to 170.5 per 100,000 (12%), gonorrhea has risen from 55.8 to 71.5 per 100,000 (28%), and P&S syphilis has risen from 4.9 to 9.8 per 100,000 (100%).

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 Nevada County.
Local HIV snapshot
Nevada County HIV care continuum (2023)
Among Nevada County residents living with HIV, 81.5% are in care · 71.5% 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 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 Nevada County tests for syphilis.

Data & references
Local context
Empire Mine State Historic Park anchors the eastern edge of town, and for many Grass Valley residents the practical question of getting screened is less about willingness than about logistics: how far, how long, and whether the day allows it. The rental picture here tells part of that story. Most residents rent rather than own, and at around a thousand dollars a month that cost sits close enough to the edge that an unexpected bill, even a small one, changes the week. Fewer than one in seven households clears six figures, so sliding-scale fees and no-cost options listed on this page carry real weight.
The household structure adds another layer: with well over half of adults not married and an average household running nearly three people, many residents are navigating shared living arrangements and overlapping social networks, exactly the kind of setting where routine STI screening becomes practical rather than precautionary. Young adults in their late teens and twenties make up a meaningful share of Grass Valley's population, and for that crowd the barrier is usually time and access, not intention. With a labor-force participation rate below the national norm and unemployment running high, schedules here can be irregular in both directions: some people are stretched across multiple part-time jobs, others have stretches of free time that still don't translate into appointments made.
Getting there
At 7.51/20 on the EPA walkability index, day-to-day errands in Grass Valley generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
