Boulder Valley Health Center tests for gonorrhea, chlamydia, syphilis, herpes, hepatitis C, and HIV on a sliding-scale fee open to anyone; bacterial infections can be treated the same visit. Appointments are required.
Boulder Valley Health Center tests for both herpes and hepatitis C alongside the standard four, which means a single visit can surface infections that a narrower panel would leave undetected, and treatment or management can begin without an additional appointment elsewhere.
Without PrEP or PEP available at the clinic you already see, prevention becomes a separate errand. A second appointment, a second provider, a gap during which exposure risk continues. Boulder Valley Health Center prescribes both, closing that gap at the same location where testing and treatment happen.
Spanish-language care at Boulder Valley Health Center operates at the clinical level: providers conduct exams, discuss medication protocols, and explain diagnoses in Spanish, so nothing is filtered through a secondary layer before it reaches the patient.

STD stats & rates
How reported STI rates in Boulder County, the county that includes Lyons, compare with Colorado and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~7% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#21 of 64 Colorado counties for chlamydia, a higher rate than 67% of the state
| Infection | Boulder County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 326.2 1,066 cases ▼ 25% | 435.1 | 492.2 |
| Gonorrhea | 74.4 243 cases ▼ 42% | 128.7 | 179.5 |
| Syphilis (P&S) | 5.2 17 cases ▼ 67% | 16 | 15.8 |
| Syphilis (early) | 2.4 8 cases ▼ 77% | 10.4 | 16 |
| Syphilis (late/unknown) | 5.5 18 cases ▼ 81% | 28.4 | 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 Boulder County, chlamydia has fallen from 338.6 to 326.2 per 100,000 (4%), gonorrhea has risen from 66.2 to 74.4 per 100,000 (12%), and P&S syphilis has fallen from 6.7 to 5.2 per 100,000 (22%).

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 Boulder County.
Local HIV snapshot
Boulder County HIV care continuum (2023)
Boulder County recorded 5.2 new HIV diagnoses per 100,000 (2023), against 9.6 statewide and 13.7 nationally. Among Boulder County residents living with HIV, 63.4% are in care · 59.2% 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 Boulder County tests for syphilis.

Local resources & officials
Data & references
Local context
Lyons moves to the rhythm of the land: ranching, construction, small-scale agriculture, and the seasonal demands that shape life in the foothills. For people who've chosen to stay or build here, that steadiness brings community but also a particular kind of visibility. Testing for STIs in and around Lyons reflects this reality: the clinics and providers listed on this page offer the discretion that matters when you know most of the faces in town. Young adults navigating early careers or establishing households here often value straightforward, confidential screening as part of staying healthy, and many households span generations under one roof, which reinforces why privacy in medical decisions carries real weight. The geography helps.
Steamboat Mountain and Indian Lookout Mountain frame a landscape that feels contained, almost intimate, yet the valley sits within reach of Boulder County resources. Testing sites available in and around Lyons range from urgent-care settings to dedicated health clinics, each with its own approach to scheduling and results delivery. What matters most to residents here is knowing that a test stays between you and your provider, not whispered over coffee, not noted in a place where word travels. That assurance, combined with the practical clinics nearby, means screening becomes as routine as it should be, regardless of how small the town feels.

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 Colorado 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 Colorado, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Colorado 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.
