Fees & payment
Bel-Red Internal Medicine in Redmond pairs gonorrhea, chlamydia, syphilis, hepatitis B and C, and HIV testing with same-visit bacterial treatment, PrEP, and PEP. All on a fee-for-service basis with appointments required.
Bel-Red's standing as an internal medicine practice means PrEP and PEP are prescribed, monitored, and followed up by the same provider over time. The right fit for someone who wants prevention medication managed within a continuous care relationship rather than a one-off visit.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Bel-Red tests for both hepatitis B and hepatitis C in the same appointment. Hepatitis C is identified through antibody testing and any reactive result can be managed directly within the practice, keeping follow-up care with the provider who ordered the test.

STD stats & rates
How reported STI rates in King County, the county that includes Carnation, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% 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
WA 203 threads through Carnation as Tolt Avenue before bending south toward Fall City, and the town strung along it is notably rooted: four in five households own their homes, many of them in established pockets like Blakely Woods, and the majority of adults here are married with households that average nearly three people. That kind of stability shapes daily life in ways worth understanding when it comes to sexual health, because it can make routine screening feel less urgent than it actually is. More than half of local households clear six figures, yet the cost of staying on top of preventive care still adds up, and for the roughly one in five residents who rent, that monthly payment leaves less room for anything that feels optional.
Younger adults, people in their late teens and twenties forming new relationships or returning to dating, face the highest likelihood of a new STI exposure and the most to gain from regular testing. Knowing in advance which sites offer sliding-scale fees or shorter appointment windows takes the guesswork out of that trip. Nick Loutsis Park on one end of town and Remlinger Farms on the other mark a community that mostly stays close to home, so building a testing visit into an errand run along Tolt Avenue is a practical approach most residents are already set up to take.
Getting there
At 6.98/20 on the EPA walkability index, day-to-day errands in Carnation 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.
