San Joaquin County reports about 18 syphilis cases per 100,000 residents, near the US average. If you have a one-time concern or want regular check-ups in Lodi, California, consider that some clinics take walk-ins for same-day testing, while labs and at-home kits let you plan around your own time. Use the list below to weigh your options.
Available testing centers
12 testing options are listed for Lodi, CA. The nearest, Quest Diagnostics, is about 0.3 miles away. Compare community and public clinics, private labs, and at-home kits below.
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.

Community Medical Centers in Lodi runs on a sliding scale, also accepting Medicaid and Medicare, and tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and TB. With same-visit treatment for bacterial STIs and hepatitis A and B vaccines available. Appointments are required.
Skipping herpes from a standard panel means leaving with answers on four infections and a separate appointment somewhere else for the fifth. Community Medical Centers tests for herpes alongside the full bacterial panel, so one visit in Lodi resolves the complete picture rather than splitting it across two.
Many clinics route Spanish-language needs through workarounds that sit outside the clinical conversation itself. At Community Medical Centers in Lodi, Spanish is spoken directly by staff: meaning the conversation about symptoms, history, and treatment happens in the room, not around it.

Planned Parenthood Mar Monte in Stockton tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee with no appointment required. Walk-in visits cover same-visit treatment for bacterial infections, HPV vaccination, and PrEP.
Spanish is spoken directly at this location, and interpretation services extend care to additional languages across every clinical interaction. That operational reach means counseling, test results, and treatment instructions land in the language a person reasons in. Without routing communication through a secondary step.
As a Title X clinic, Planned Parenthood Mar Monte is legally required to keep reproductive and STI services for minors confidential. Meaning a billing notice or summary cannot be sent to a parent or guardian. That protection is structural, not discretionary.
Prevention-focused clinics often test but stop short of prescribing antiretrovirals, leaving patients to source PrEP or PEP through a separate provider. Planned Parenthood Mar Monte prescribes both directly, keeping HIV prevention consolidated within the same clinical relationship as testing.

STD stats & rates
How reported STI rates in San Joaquin County, the county that includes Lodi, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~29% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#10 of 58 California counties for chlamydia, a higher rate than 83% of the state
| Infection | San Joaquin County | California | United States |
|---|---|---|---|
| Chlamydia | 529.6 4,242 cases ▲ 8% | 491.1 | 492.2 |
| Gonorrhea | 156.8 1,256 cases ▼ 18% | 190.2 | 179.5 |
| Syphilis (P&S) | 17.5 140 cases ▲ 7% | 16.3 | 15.8 |
| Syphilis (early) | 24.3 195 cases ▲ 27% | 19.1 | 16 |
| Syphilis (late/unknown) | 58.1 465 cases ▲ 24% | 46.7 | 29.5 |

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 San Joaquin County, chlamydia has risen from 465.3 to 529.6 per 100,000 (14%), gonorrhea has fallen from 185.7 to 156.8 per 100,000 (16%), and P&S syphilis has fallen from 23.6 to 17.5 per 100,000 (26%).

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 San Joaquin County.
Local HIV snapshot
San Joaquin County HIV care continuum (2023)
San Joaquin County recorded 15.4 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among San Joaquin County residents living with HIV, 76% are in care · 68.5% 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 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 San Joaquin County tests for syphilis.

Local resources & officials
Data & references
Local context
CA 12, West Kettleman Lane, is the spine most Lodi residents travel to reach practically anything outside the city core, and a clinic visit typically means following it out of town and back, carving a real block of time out of a workday or weekend. That kind of trip carries more weight in a city where roughly seven in ten working-age adults are in the labor force and unemployment runs notably higher than many California neighbors, leaving schedules tighter and discretionary hours scarcer than the numbers might suggest at first. The household picture here adds texture.
With just over a quarter of households earning six figures, rent hovering above a thousand dollars a month for nearly half of all residents, and an average household nudging past three people, cost and space tend to be active considerations in most families' decisions, not background noise. Lodi leans toward owned homes by a slim margin, but renters are nearly as numerous, and both groups share the same practical reality: a testing appointment competes with work shifts, childcare, and the ordinary demands of a full house. That reality lands hardest on the sizable share of residents in their late teens and twenties, the years when STI exposure is statistically most likely and when life tends to move fast across jobs, relationships, and living arrangements.
Getting there
Lodi scores 10.79/20 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.

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.
