HealthPoint in Auburn delivers gonorrhea, chlamydia, syphilis, HIV, and TB testing with same-visit treatment for bacterial infections when needed. Fees run on a sliding scale accepted alongside Medicaid, Medicare, and private insurance. Appointments are required.
HealthPoint carries interpretation services for non-English languages directly into the clinical encounter, not as an add-on arranged after the fact. That integration means test counseling, PrEP discussions, and STI treatment decisions all happen in the language a patient communicates in without delay or friction.
Many STI testing sites assess HIV risk and leave patients to find a prescriber on their own. HealthPoint in Auburn writes PrEP prescriptions in-house, closing the gap between a positive risk assessment and an actual prevention regimen.
HealthPoint operates substance-use treatment as a named clinical service on the same campus as its STI program. That structural pairing means a patient managing both concerns doesn't carry a secondary referral into an entirely separate system, the coordination is already built in.

STD stats & rates
How reported STI rates in King County, the county that includes Black Diamond, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#18 of 39 Washington counties for chlamydia, a higher rate than 54% of the state
| Infection | King County | Washington | United States |
|---|---|---|---|
| Chlamydia | 324 7,360 cases ▼ 9% | 354.4 | 492.2 |
| Gonorrhea | 198.5 4,509 cases ▲ 53% | 129.6 | 179.5 |
| Syphilis (P&S) | 25.4 578 cases ▲ 19% | 21.3 | 15.8 |
| Syphilis (early) | 18 409 cases ▲ 44% | 12.5 | 16 |
| Syphilis (late/unknown) | 29.1 660 cases ▲ 27% | 22.9 | 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 King County, chlamydia has fallen from 373.4 to 324 per 100,000 (13%), gonorrhea has risen from 192 to 198.5 per 100,000 (3%), and P&S syphilis has risen from 14.8 to 25.4 per 100,000 (72%).

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 King County.
Local HIV snapshot
Federal priority area: King County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
King County HIV care continuum (2023)
King County recorded 9 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among King County residents living with HIV, 88% know their status · 87% are in care · 79.1% 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 King County tests for syphilis.

Data & references
Local context
Lawson Hill Estates and Tamerron are neighborhoods built for the long haul: most households here own their homes, and nearly two-thirds of adults are married with families averaging close to three people. That stability shapes daily life in ways that can quietly sideline personal health appointments: dual schedules, school pickups, and commutes out along WA 169 mean that anything requiring a dedicated trip gets weighed against everything else competing for the same afternoon. That calculus matters most for people in their late teens and twenties: the years when relationship patterns are shifting, new partnerships are forming, and routine screening is genuinely useful but rarely feels urgent.
With more than half of Black Diamond households earning above six figures and unemployment low, financial pressure isn't the primary hurdle for most residents. The likelier barrier is simply time: a workforce participation rate that reflects a town where nearly everyone is working, often outside city limits. A few of the options listed on this page are reachable without a car or a long drive down the Maple Valley Black Diamond Road Southeast, and for anyone squeezing a health visit into a Tuesday between work and dinner, that difference between a five-minute walk and a forty-minute round trip is often what determines whether the appointment happens at all.
Getting there
At 5.9/20 on the EPA walkability index, day-to-day errands in Black Diamond 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 Washington 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 Washington, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Washington 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.
