Stony Brook Medicine brings academic medical infrastructure to STI care in Stony Brook, covering the full panel (HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C) with same-visit treatment for bacterial infections, sliding-scale fees, and appointments required. All services are provided at no fee.
HIV testing and hepatitis C testing are explicitly free at Stony Brook Medicine, and that zero-fee policy extends across the entire service menu. No fee accrues regardless of what the visit covers, which means PrEP monitoring, hepatitis treatment, and TB care all fall under the same cost structure.
Plenty of testing sites screen for HIV without offering the drugs that prevent it. Stony Brook Medicine prescribes both PrEP, the daily antiretroviral regimen, and PEP, extending prevention from a single test into an ongoing clinical relationship rather than a handoff.
A positive hepatitis C test at Stony Brook Medicine doesn't end the encounter, the clinic carries treatment on-site. Direct-acting antivirals, which clear hepatitis C in the overwhelming majority of cases, are managed here, meaning diagnosis and the full treatment course stay within the same system.

Stony Brook Extended Care in Centereach covers gonorrhea, chlamydia, syphilis, herpes, hepatitis B and C, HIV, and TB. With same-visit treatment for bacterial STIs and sliding-scale fees that extend to Medicare and Medicaid; appointments are required.
Stony Brook Extended Care tests for herpes simplex and both hepatitis B and C alongside the standard bacterial and HIV panel, six distinct pathogens beyond TB. A single appointment can surface infections that a narrower panel would leave undetected and therefore unmanaged.
Hepatitis C treatment is available on-site at Stony Brook Extended Care in Centereach, meaning a confirmed diagnosis leads directly to a treatment plan within the same practice. No hand-off to a separate specialist before care begins.
Without an on-site prescriber for PrEP or PEP, the gap between deciding to start and actually starting can stretch into weeks. Stony Brook Extended Care closes that gap, both medications are prescribed here, so prevention isn't deferred to a second appointment elsewhere.

Sun River Health in Coram runs on sliding-scale fees with Medicaid, Medicare, and private insurance accepted, and PrEP is available for the uninsured.

Sun River Health in Coram employs staff fluent in Spanish and holds ASL capacity on-site, and interpretation services are available for additional languages. Meaning the clinician explaining your hepatitis C treatment plan or walking through PrEP dosing is working in your language directly, not through a relay.
Without Ryan White funding, a positive HIV result often triggers a handoff. Leaving patients to navigate costs and wait times at a separate provider. Sun River Health in Coram uses Ryan White to carry patients from initial testing through ongoing HIV medical treatment and medication adherence counseling within the same practice.
Going without PrEP while waiting for a separate prescriber means real, accumulating exposure risk. Sun River Health in Coram prescribes and monitors both PrEP and PEP directly, with PrEP available for uninsured patients, so prevention isn't deferred to another practice or another day.

STD stats & rates
How reported STI rates in Suffolk County, the county that includes Port Jefferson, compare with New York and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#19 of 62 New York counties for chlamydia, a higher rate than 69% of the state
| Infection | Suffolk County | New York | United States |
|---|---|---|---|
| Chlamydia | 342.5 5,217 cases ▼ 39% | 558.4 | 492.2 |
| Gonorrhea | 70.5 1,074 cases ▼ 70% | 235.6 | 179.5 |
| Syphilis (P&S) | 5.8 89 cases ▼ 61% | 14.8 | 15.8 |
| Syphilis (early) | 11 167 cases ▼ 52% | 23.1 | 16 |

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 Suffolk County, chlamydia has risen from 314.4 to 342.5 per 100,000 (9%), gonorrhea has risen from 69.3 to 70.5 per 100,000 (2%), and P&S syphilis has risen from 3.9 to 5.8 per 100,000 (49%).

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 Suffolk County.
Local HIV snapshot
Suffolk County HIV care continuum (2023)
Suffolk County recorded 6.2 new HIV diagnoses per 100,000 (2023), against 14.1 statewide and 13.7 nationally. Among Suffolk County residents living with HIV, 82.4% are in care · 77.3% 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 Suffolk County tests for syphilis.

Data & references
Local context
Route 25A threads through Port Jefferson's core and into the quieter residential stretches toward Miller Place and Terryville, where homeownership runs deep and household budgets are anchored to mortgages rather than rent. That ownership culture shapes daily life in a particular way: schedules fill up around school runs, commutes, and the kind of extended-family households that average more than three people under one roof. With more than half of adults married and a labor-force participation rate that leaves relatively little slack time in the week, carving out a midday appointment can feel genuinely difficult, even for something as brief as STI screening. That matters most for young adults in their late teens and twenties, who account for a meaningful slice of Port Jefferson's population and fall squarely in the years when STI rates run highest.
Suffolk County's STI figures, visible elsewhere on this page, give that context local weight. Over half of Port Jefferson households bring in six figures, but between a mortgage near the area's median home value and expenses running across a family of three, out-of-pocket testing costs still factor into the decision for many people. Knowing the fee structure before you go removes one less reason to put it off.
Getting there
At 8.47/20 on the EPA walkability index, day-to-day errands in Port Jefferson generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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