See the options below.
Available testing centers
12 testing options are listed for Trenton, NJ. The nearest, Labcorp, is about 0.1 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

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.

Henry J. Austin Health Center at Oaks Integrated Care in Trenton welcomes walk-in patients for STI screening under its federally qualified health center charter, covering syphilis, gonorrhea, and chlamydia in a single visit. Fees follow a sliding scale tied to income, so cost adjusts to what each patient can pay.

Henry J. Austin Health Center at the Rescue Mission of Trenton earns its federally qualified designation partly by tying STI screening fees to each patient's actual income: meaning syphilis, gonorrhea, and chlamydia testing stays within reach regardless of what someone earns. No appointment is needed to get started.

Planned Parenthood of Northern Central and Southern in Trenton, offers walk-in testing for gonorrhea, syphilis, herpes, chlamydia, and HIV on a sliding-scale fee, with same-visit treatment for bacterial infections, and staff who speak Spanish and access interpretation for other languages.
For anyone navigating an STI visit without strong English (whether discussing symptoms, understanding a result, or weighing PrEP) the clinic's Spanish-speaking staff and available interpretation mean the conversation happens fully, not in shorthand. Nothing gets compressed into a nod and a guess.
Many family planning providers quietly sidestep minors seeking confidential care, leaving a real gap. As a Title X site, Planned Parenthood of Northern Central and Southern New Jersey is legally required to provide confidential services to minors. No parental disclosure, no workaround.
Both PrEP and PEP are prescribed directly at this Trenton location, which means a patient who decides to start HIV prevention leaves with a plan. Not a name to call later.

Hamilton Township Division of Health in Hamilton takes walk-ins for its full testing menu (gonorrhea, chlamydia, syphilis, rapid and conventional HIV, hepatitis B and C, herpes, and TB) plus same-visit treatment for bacterial infections, with every test and service provided at no fee.
The Division of Health operates on a no-fee structure that isn't limited to a subset of services or income tiers: testing, treatment, vaccines, and counseling are all billed at zero dollars. That means the Mpox, HPV, and hepatitis A and B vaccines carry the same cost as the HIV test: nothing.
Interpretation services are available for non-English languages, which means clinical conversations (exposure history, medication adherence counseling, test results) happen in full rather than in abbreviated English. Counseling that depends on nuance isn't compromised by a language gap.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Hamilton Township tests for herpes, hepatitis B, and hepatitis C in the same visit. Meaning infections that often go undetected for years are caught at the same appointment rather than requiring a separate referral to a different provider.

STD stats & rates
How reported STI rates in Mercer County, the county that includes Trenton, compare with New Jersey 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.
#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 |

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.

Local resources & officials
Data & references
Local context
Pennington Avenue cuts through a city where most households rent rather than own, and where the average home holds nearly four people under one roof. That density shapes how health decisions get made: in a household of that size, a conversation about testing is rarely a private calculation. With fewer than three in ten adults married and a relatively small share of households in the higher income brackets, the financial math around discretionary health visits is real, and the options listed on this page include sliding-scale and low-cost appointments that fit that reality.
A substantial share of Trenton residents are not currently in the labor force, and those who are working contend with an unemployment rate that keeps budgets tight across neighborhoods like Battle Monument and Mill Hill. Young adults in their late teens and twenties, who make up a meaningful portion of the population, are at the ages when STI exposure is most common, and they are also the group most likely to defer a clinic visit when the cost or the logistics feel uncertain. For someone renting near North Broad Street on a household income well below the six-figure threshold most residents never reach, a same-week appointment with transparent fees is the version of care that actually gets used.
Mercer County's STI figures reflect the cumulative effect of deferred screening across communities exactly like this one. For a Trenton resident, staying current with testing is less an abstract health principle than a direct response to what the county data already shows.
Getting there
Trenton scores 13.97/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
