Collin County, Texas has new HIV diagnoses running about 22% lower than the US average. If you live in St. Paul, Texas and are considering STI testing whether you have symptoms or not, decide if you'd rather visit a local clinic that may use insurance, or go to one of the private labs with flat self-pay pricing. See the options listed below.
Available testing centers
7 testing options are listed for St. Paul, TX. The nearest, Quest Diagnostics, is about 4.2 miles away. Compare community and public clinics, private labs, and at-home kits below.
Texas Infectious Disease Institute in Richardson tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and all three hepatitis strains, and treats bacterial STIs at the same appointment. Fees run on a sliding scale, with insurance and Medicaid accepted. Care is available in French and Spanish.
Plenty of clinics will run a hepatitis C antibody test and leave patients to find a specialist for what comes next. Texas Infectious Disease Institute closes that gap, antiviral treatment for hepatitis C is managed on-site, so a confirmed diagnosis moves directly into a care plan without a separate provider search.
PrEP at Texas Infectious Disease Institute means a prescription for daily oral medication alongside the regular HIV and kidney-function monitoring the regimen requires. PEP is similarly prescribed and followed here. Both are available to uninsured patients through sliding-scale fees, keeping the clinical relationship, not just the initial script, intact.
When a clinic can't conduct a visit in a patient's language, the workaround costs time and sometimes accuracy. A misread symptom, a misunderstood dosing schedule, a follow-up that doesn't happen. Texas Infectious Disease Institute holds clinical conversations directly in French and Spanish, so nothing in a care plan gets filtered through an intermediary.

Julias Center for Healthcare in Plano runs its full STI panel (gonorrhea, chlamydia, syphilis, conventional HIV, hepatitis B and C, and TB) with appointments required and a fee structure that accepts donations, scales to income, or waives cost entirely.
The no-fee structure at Julias Center for Healthcare isn't a waiver applied after a means test: it's the baseline rate for every service on the menu, from the initial panel to STI treatment and vaccines. Staff deliver care against that same price floor regardless of what brought someone in.
Julias Center for Healthcare tests for hepatitis B and C in addition to gonorrhea, chlamydia, syphilis, and HIV. Meaning a single visit can surface a hepatitis infection that would otherwise go undetected until it showed up in a separate workup somewhere else.

STD stats & rates
How reported STI rates in Collin County, the county that includes St. Paul, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#154 of 254 Texas counties for chlamydia, a higher rate than 39% of the state
| Infection | Collin County | Texas | United States |
|---|---|---|---|
| Chlamydia | 256.8 3,070 cases ▼ 48% | 491.9 | 492.2 |
| Gonorrhea | 86.3 1,032 cases ▼ 51% | 176.4 | 179.5 |
| Syphilis (P&S) | 6.3 75 cases ▼ 58% | 15 | 15.8 |
| Syphilis (early) | 16.3 195 cases ▼ 38% | 26.4 | 16 |
| Syphilis (late/unknown) | 8.4 100 cases ▼ 81% | 44.3 | 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 Collin County, chlamydia has risen from 221.5 to 256.8 per 100,000 (16%), gonorrhea has risen from 76.8 to 86.3 per 100,000 (12%), and P&S syphilis has risen from 2.1 to 6.3 per 100,000 (200%).

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 Collin County.
Local HIV snapshot
Collin County HIV care continuum (2023)
Collin County recorded 10.7 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Collin County residents living with HIV, 79.9% are in care · 70.5% 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 Collin County tests for syphilis.

Data & references
Local context
St. Paul takes its name from the church that anchored the settlement, and that sense of rootedness still defines the place. Families who own their homes for decades, who know their neighbors across generations, who build their lives here intentionally. That stability matters when it comes to health decisions, especially ones that feel private.
Testing for sexually transmitted infections in and around St. Paul is available through the clinics and providers listed on this page, and the confidentiality you receive there is absolute; what you learn about your status stays between you and the medical staff, regardless of how connected the community feels. Young adults in their late teens through their thirties make up a significant part of St. Paul's population, and many of them are at the stage of life when routine screening (whether you're starting a new relationship, between partners, or simply being thorough) becomes straightforward and essential.
The testing sites serving the area understand that people in this age range often have questions about what's involved, how quickly results come back, and what happens next if treatment is needed. Collin Park and the neighborhoods of Wylie and Lucas all have access to the same confidential testing services listed here. Whether you live in town proper or out along FM 544 or the State Highway corridors, the clinics available to you treat sexual health as routine medicine, not as something that carries shame or requires explanation.
Getting there
At 6.33/20 on the EPA walkability index, day-to-day errands in St. Paul generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Two things that actually depend on Texas 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 Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Texas 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.
