My Choice Medical Clinic in Butler delivers STI testing (HIV, syphilis, gonorrhea, chlamydia, hepatitis B, and hepatitis C) through a medical clinic framework where STI treatment, counseling, and prevention education sit alongside testing, all at no fee to you, with no appointment required.
For anyone paying cash, between coverage, or simply without a regular provider, My Choice Medical Clinic carries the full weight: testing, treatment, counseling, and prevention education are all provided at no fee. There is no tier of services that costs more, no point at which a fee appears.
Hepatitis B and C can circulate silently alongside bacterial STIs, and chasing them down separately (a second visit, a second provider, an added cost) creates real gaps in care. My Choice Medical Clinic tests for both hepatitis B and hepatitis C as part of its panel, free, so that gap never opens.

STD stats & rates
How reported STI rates in Butler County, the county that includes Karns City, compare with Pennsylvania and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~19% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#45 of 67 Pennsylvania counties for chlamydia, a higher rate than 33% of the state
| Infection | Butler County | Pennsylvania | United States |
|---|---|---|---|
| Chlamydia | 169.8 337 cases ▼ 60% | 421.2 | 492.2 |
| Gonorrhea | 20.2 40 cases ▼ 86% | 144.7 | 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 Butler County, chlamydia has fallen from 192 to 169.8 per 100,000 (12%), gonorrhea has fallen from 40.8 to 20.2 per 100,000 (50%), and P&S syphilis has risen from 1.5 to 3 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 Butler County.
Local HIV snapshot
Butler County HIV care continuum (2023)
Butler County recorded 0 new HIV diagnoses per 100,000 (2023), against 8.3 statewide and 13.7 nationally. Among Butler County residents living with HIV, 83.1% are in care · 65.3% 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 Butler County tests for syphilis.

Two things that actually depend on Pennsylvania 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 Pennsylvania, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Pennsylvania 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.
