Available testing centers
9 testing options are listed for Old Westbury, NY. The nearest, New York Institute of Technology, is about 1.6 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.

New York Institute of Technology's Greenvale clinic folds STI care into a campus health setting, covering gonorrhea, chlamydia, syphilis, herpes, and HIV by appointment, with fees billed to insurance or charged on a sliding scale, and PrEP and PEP for prevention.
NYIT Greenvale prescribes both PrEP and PEP on-site, meaning a conversation about prevention and a prescription happen in the same visit. That continuity keeps long-term PrEP management (refills, monitoring labs, follow-up) anchored to one clinical relationship.
For anyone without a regular provider who wants a thorough baseline, or who pays out of pocket and needs answers without piecing together multiple appointments, NYIT Greenvale's panel adds herpes to gonorrhea, chlamydia, syphilis, and HIV, covering infections that many clinic panels quietly omit.

Harmony Healthcare Long Island in Westbury schedules appointments for STI care that spans the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, TB, and rapid or conventional HIV) with same-visit treatment for bacterial infections, sliding-scale fees, and Spanish-language services throughout.
Spanish is a complete service language at Harmony Healthcare Long Island, not a supplemental accommodation. Every stage of care, from HIV test counseling to STI treatment conversations, runs in Spanish, which means clinical nuance and follow-through aren't compressed by translation lag.
Plenty of STI clinics test and treat but stop well short of ongoing HIV prevention prescribing. Harmony Healthcare Long Island carries both PrEP and PEP, including PrEP coverage for uninsured patients, making antiviral prevention a standing clinical offering rather than something sourced elsewhere.
Harmony Healthcare Long Island integrates substance-use treatment directly into its care model alongside STI and TB services. That co-location matters clinically: conditions that share risk pathways (hepatitis C infection and injection drug use, for instance) can be addressed within the same ongoing care relationship rather than across disconnected programs.

Northwell Health-GoHealth Urgent Care in Greenvale takes walk-ins for a full STI panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, plus TB) with same-visit treatment for bacterial infections, HPV and hepatitis vaccines, and fees billed to insurance or Medicaid.
Chasing a herpes diagnosis or hepatitis result through a separate lab or specialist appointment means a second scheduling loop, a second copay, and days more waiting. Northwell Health-GoHealth Urgent Care in Greenvale tests for herpes and all three hepatitis strains (A, B, and C) alongside the bacterial panel, so one visit closes those gaps rather than opening new ones.
Plenty of urgent-care settings treat non-English speakers as an afterthought: a later call, a rescheduled visit, or a stripped-down consultation. Northwell Health-GoHealth Urgent Care in Greenvale has interpretation services on hand during the visit itself, so the conversation about symptoms, results, and next steps happens fully, not in fragments.

Catholic Health Physician Partners in East Hills accepts Medicaid, Medicare, and private insurance, with a separate PrEP program for uninsured patients. Appointments cover gonorrhea, chlamydia, syphilis, herpes, HIV, hepatitis B and C, and TB, with same-visit treatment for bacterial STIs.
Chasing PrEP or PEP across multiple providers means gaps, in coverage, in timing, in follow-through. Catholic Health Physician Partners prescribes both prevention medications directly, so the clinical relationship that started with a test doesn't have to fragment the moment prevention becomes the next step.
Catholic Health Physician Partners carries hepatitis C treatment on-site, direct-acting antivirals managed within the same practice that ran the hepatitis C antibody and confirmatory RNA testing. Keeping treatment in-house means monitoring and dosing adjustments happen without handing the patient off to a separate specialist.
Catholic Health Physician Partners tests for herpes and both hepatitis B and C in addition to gonorrhea, chlamydia, syphilis, and HIV, which means infections that a shorter panel would miss are caught at the same appointment, opening the door to treatment before they progress silently.

STD stats & rates
How reported STI rates in Nassau County, the county that includes Old Westbury, compare with New York and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~46% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#22 of 62 New York counties for chlamydia, a higher rate than 65% of the state
| Infection | Nassau County | New York | United States |
|---|---|---|---|
| Chlamydia | 328.3 4,536 cases ▼ 41% | 558.4 | 492.2 |
| Gonorrhea | 70.1 968 cases ▼ 70% | 235.6 | 179.5 |
| Syphilis (P&S) | 7.7 107 cases ▼ 48% | 14.8 | 15.8 |
| Syphilis (early) | 10.9 150 cases ▼ 53% | 23.1 | 16 |
| Syphilis (late/unknown) | 9.2 127 cases ▼ 63% | 25.2 | 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 Nassau County, chlamydia has risen from 299 to 328.3 per 100,000 (10%), gonorrhea has risen from 67 to 70.1 per 100,000 (5%), and P&S syphilis has risen from 3.6 to 7.7 per 100,000 (114%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Nassau County.
Local HIV snapshot
Nassau County HIV care continuum (2023)
Nassau County recorded 6.9 new HIV diagnoses per 100,000 (2023), against 14.1 statewide and 13.7 nationally. Among Nassau County residents living with HIV, 78.4% are in care · 74.2% 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 Nassau County tests for syphilis.

Data & references
Local context
Westbury House's grounds and the quiet lanes around Spring Hill at Old Westbury project a permanence that matches the area's overwhelmingly owner-occupied housing stock: nearly everyone here has planted roots, and household sizes run well above the national average. That stability shapes daily rhythms in ways that matter for healthcare access: with most adults in this zip code outside the traditional workforce at any given time, and a meaningful share managing unemployment right now, the flexibility to schedule a screening appointment mid-week is real for some residents but genuinely compressed for others still holding jobs. Nassau County's STI trends make timely testing relevant for the substantial slice of Old Westbury residents in their late teens and twenties, years when relationship patterns shift and routine screening pays dividends that show up years later.
What's less automatic is cost. With the vast majority of households here earning well above six figures, out-of-pocket fees at many listed clinics register as minor. But for the small renter population or any resident currently between jobs, the same appointment carries a different weight, and knowing which listed options offer sliding-scale fees or accept Medicaid can make a real difference in whether screening happens at all.

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.
