A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Optum in Springfield Township folds STI care into a full-service medical practice, pairing the standard panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B and C) with same-visit bacterial treatment, sliding-scale fees, and Spanish-language care.
Many clinics handle Spanish through workarounds that sit outside the clinical encounter itself. At Optum, Spanish is a language of the visit: history, counseling, and treatment discussion conducted directly, without a layer between patient and provider. That continuity changes what can actually be said and understood.
Optum prescribes both Truvada and Descovy for PrEP, managing the required HIV testing and renal monitoring that the regimen demands on an ongoing basis. PEP is likewise available as a standing clinical service, not a one-time referral but a capability the practice maintains.
For someone managing hepatitis C without a specialist relationship, Optum's standing capability to prescribe and monitor direct-acting antiviral therapy is the difference between a diagnosis sitting on paper and a cure in reach. Testing, confirmation, and treatment are handled within the same practice.

Iris House in Plainfield tests for HIV, syphilis, gonorrhea, chlamydia, and hepatitis C at no charge to anyone who walks through the door. Sliding-scale simply means zero here. Spanish-language care and an appointment-based model keep visits focused and unhurried.
Fee schedules, income verification, insurance checks. Many clinics build the cost question into the visit before the clinical one. Iris House doesn't. Every test, every counseling session, every self-test kit carries no charge, full stop, for everyone.
Iris House delivers care in Spanish as a standing clinical capability: counseling, test results, and medication adherence education conducted directly in the language, not routed through a secondary channel. For someone navigating HIV prevention or an unexpected result without a regular English-speaking provider, that directness changes the quality of every conversation.
Leaving Iris House without a hepatitis C result often means scheduling elsewhere, waiting on a referral, and letting a potentially active infection sit unconfirmed. Iris House tests for hepatitis C alongside HIV, syphilis, gonorrhea, and chlamydia, so nothing requires a follow-up trip to answer the question this visit already raised.

STD stats & rates
How reported STI rates in Union County, the county that includes Mountainside, compare with New Jersey and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~12% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#8 of 21 New Jersey counties for chlamydia, a higher rate than 62% of the state
| Infection | Union County | New Jersey | United States |
|---|---|---|---|
| Chlamydia | 452.7 2,593 cases ▲ 18% | 384.1 | 492.2 |
| Gonorrhea | 131.8 755 cases ▲ 21% | 109.1 | 179.5 |
| Syphilis (P&S) | 10.1 58 cases ▲ 25% | 8.1 | 15.8 |
| Syphilis (early) | 10.5 60 cases ▲ 1% | 10.4 | 16 |
| Syphilis (late/unknown) | 19 109 cases ▲ 19% | 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 Union County, chlamydia has risen from 395.8 to 452.7 per 100,000 (14%), gonorrhea has risen from 116.5 to 131.8 per 100,000 (13%), and P&S syphilis has fallen from 11.8 to 10.1 per 100,000 (14%).

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 Union County.
Local HIV snapshot
Union County HIV care continuum (2023)
Union County recorded 18.6 new HIV diagnoses per 100,000 (2023), against 11.9 statewide and 13.7 nationally. Among Union County residents living with HIV, 68.8% are in care · 62.6% 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 Union County tests for syphilis.

Local resources & officials
Data & references
Local context
Dundar Road cuts through a borough where apartments rarely dip below $1,700 a month, a financial ceiling that shapes how younger adults in Mountainside weigh every discretionary expense, including healthcare. For someone navigating a new relationship or a coverage gap between jobs, a medical appointment can feel like one more line item to defer. That calculus matters here, where the slice of residents in their late teens and twenties, the years when STIs circulate most actively, is smaller than in denser neighboring towns, yet the exposure risk those years carry doesn't shrink with the zip code. Mountainside's household profile leans heavily toward long-term homeowners and established families, with nearly two-thirds of adults married and average households of three or more people.
That stability is real, but it sits alongside a workforce participation rate that leaves meaningful room for people outside traditional employment: managing irregular hours, patched-together coverage, or income gaps that make routine care easy to skip. The testing options listed here include choices that work around those constraints. For everyone else, the range of listed clinics along the I-78 corridor keeps a same-week appointment genuinely within reach.
Getting there
Mountainside scores 13.11/20 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.
