Henry J Austin Health Center in Trenton covers gonorrhea, chlamydia, syphilis, herpes, hepatitis B, hepatitis C, TB, and rapid or conventional HIV testing, bacterial infections treated the same visit, on a sliding-scale fee that extends to every service, including HIV testing at no charge. Appointments required.
Henry J Austin's sliding scale isn't capped at testing: it applies to STI treatment, PrEP, PEP, HIV/AIDS medical care, hepatitis C treatment, and both hepatitis A and B vaccines. HIV testing carries no fee outright. The result is that a single appointment can move from diagnosis to prescription without a separate billing tier activating midway.
Spanish-language services at Henry J Austin are delivered by clinical staff directly: meaning medical history, counseling, and treatment decisions happen in Spanish within the appointment itself, not routed through a separate channel. That staffing covers the full service menu, from STI counseling to HIV care management.
Ryan White funding positions Henry J Austin to serve people who need ongoing HIV medical care but lack the insurance or regular provider to sustain it: antiretroviral treatment, medication adherence counseling, and long-term management are all within scope at this clinic, not referred elsewhere after a positive result is confirmed.

STD stats & rates
How reported STI rates in Mercer County, the county that includes Pennington, compare with New Jersey and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~18% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#4 of 21 New Jersey counties for chlamydia, a higher rate than 81% of the state
| Infection | Mercer County | New Jersey | United States |
|---|---|---|---|
| Chlamydia | 505.4 1,929 cases ▲ 32% | 384.1 | 492.2 |
| Gonorrhea | 139.4 532 cases ▲ 28% | 109.1 | 179.5 |
| Syphilis (P&S) | 10.2 39 cases ▲ 26% | 8.1 | 15.8 |
| Syphilis (early) | 11 42 cases ▲ 6% | 10.4 | 16 |
| Syphilis (late/unknown) | 19.4 74 cases ▲ 21% | 16 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Mercer County, chlamydia has risen from 408.7 to 505.4 per 100,000 (24%), gonorrhea has fallen from 151.8 to 139.4 per 100,000 (8%), and P&S syphilis has risen from 8.3 to 10.2 per 100,000 (23%).

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 Mercer County.
Local HIV snapshot
Mercer County HIV care continuum (2023)
Mercer County recorded 18 new HIV diagnoses per 100,000 (2023), against 11.9 statewide and 13.7 nationally. Among Mercer County residents living with HIV, 71.5% are in care · 63.6% 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 Mercer County tests for syphilis.

Data & references
Local context
Pennington traces its name to William Penn's colonial land grants, a legacy visible in the town's commitment to stability and care. That same deliberate character shapes how residents approach health, testing included. Young adults moving into the area or establishing themselves here often seek straightforward access to confidential screening, and the clinics and providers listed on this page serve that need without fanfare or delay. The community's mix of established families and younger adults building lives in Hopewell Township and nearby neighborhoods means testing services draw on both routine preventive care and the particular openness that comes with a transient population.
Confidentiality is simply how these services operate: results remain between patient and provider, with no surprises passed along to employers, schools, or anyone else. Testing in and around Pennington reflects the town's pragmatic approach to health. Whether someone is newly sexually active, in a new relationship, or simply maintaining wellness on their own schedule, the providers available here treat screening as normal medical care: unrushed, discreet, and straightforward.

Two things that actually depend on New Jersey 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 Jersey, a minor can consent to confidential STI testing and treatment at any age, and to HIV testing at age 13 or older; a provider may notify a parent, and must do so where sexual assault is involved.
New Jersey 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.
