Chlamydia in Harris County is reported 30% higher than the US average. If you're in Houston, Texas, and considering STI testing whether for possible exposure or routine care, you can choose between community clinics with low-cost or free services and private labs that may offer faster results and more flexible scheduling. See the list below for local options.
Available testing centers
12 testing options are listed for Houston, TX. The nearest, Quest Diagnostics, is about 0.8 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.

Saint Hope Foundation in Jersey Village tests for HIV, syphilis, gonorrhea, chlamydia, hepatitis A, B, and C, herpes, and TB: all at no charge, on a sliding scale, with appointments required and same-visit treatment available for bacterial infections.
Saint Hope Foundation provides all of its services (testing, treatment, vaccines, PrEP) at no fee, which means the cost of a visit never becomes the reason someone delays care or skips a follow-up appointment.
Spanish is staffed into the clinical encounter itself: providers discuss medication schedules, lab results, and adherence counseling in Spanish without routing through a separate service, so nothing is lost between the clinical detail and the patient's understanding.
Saint Hope Foundation maintains the clinical capacity to prescribe and monitor both PrEP and PEP, which makes it a reliable option for someone paying cash or without an established primary care relationship who needs ongoing HIV prevention rather than a one-time referral.

Testing too soon can miss an infection. Enter the date of possible exposure to see the earliest a test can reliably detect each STI.
| Infection | Earliest reliable test | Conclusive after |
|---|---|---|
| Chlamydia | 7 days after exposure | 14 days after exposure |
| Gonorrhea | 7 days after exposure | 14 days after exposure |
| Trichomoniasis | 7 days after exposure | 28 days after exposure |
| HIV (NAT / RNA) | 10 days after exposure | 33 days after exposure |
| HIV (4th-gen Ag/Ab) | 18 days after exposure | 45 days after exposure |
| HIV (antibody) | 21 days after exposure | 84 days after exposure |
| Syphilis | 21 days after exposure | 42 days after exposure |
| Hepatitis B | 21 days after exposure | 42 days after exposure |
| Hepatitis C | 56 days after exposure | 77 days after exposure |
| Herpes (HSV) | 28 days after exposure | 112 days after exposure |

Every other option
Beyond the dedicated testing centers above: at-home kits by mail, hospital labs certified for STI testing, local clinicians who can order a panel during a regular visit, pharmacies for self-test kits and prescriptions, and online PrEP & treatment.
Test from home
The nearest testing center is less than a mile away; if you'd rather skip the trip, an at-home kit ships to Houston, you collect the sample privately, and mail it back to a CLIA-certified lab. Results come online in days, with a clinician available if anything is positive. Same labs as a clinic, no waiting room, and you can read how accurate at-home STD tests are before you order.
Want a free option first? The CDC-supported TakeMeHome (opens in a new tab) program mails free at-home HIV self-test kits, and, in many areas, free STI kits, to your door, with no insurance or payment needed. The paid kits below add broader panels and faster turnaround.

STD stats & rates
How reported STI rates in Harris County, the county that includes Houston, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~32% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#13 of 254 Texas counties for chlamydia, a higher rate than 95% of the state
| Infection | Harris County | Texas | United States |
|---|---|---|---|
| Chlamydia | 641.4 31,014 cases ▲ 30% | 491.9 | 492.2 |
| Gonorrhea | 240.6 11,631 cases ▲ 36% | 176.4 | 179.5 |
| Syphilis (P&S) | 28.2 1,363 cases ▲ 88% | 15 | 15.8 |
| Syphilis (early) | 40.8 1,975 cases ▲ 55% | 26.4 | 16 |
| Syphilis (late/unknown) | 57 2,756 cases ▲ 29% | 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 Harris County, chlamydia has risen from 528.4 to 641.4 per 100,000 (21%), gonorrhea has risen from 239.6 to 240.6 per 100,000 (0%), and P&S syphilis has risen from 13.3 to 28.2 per 100,000 (112%).

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 Harris County.
Local HIV snapshot
Federal priority area: Harris County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Harris County HIV care continuum (2023)
Harris County recorded 33.4 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Harris County residents living with HIV, 86.7% know their status · 75.2% are in care · 65.1% 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 Harris County tests for syphilis.

Data & references
Local context
Houston carries more homeownership than its reputation as a renter's city might suggest, yet the majority of households here still write a monthly check, and at typical rents, that leaves real limits on discretionary spending, including healthcare visits that feel optional until they aren't. That financial squeeze, spread across some of the largest average households in any major Texas city, means a single unexpected co-pay or a clinic that closes before a second shift ends can quietly shelve a screening appointment for weeks. The neighborhoods clustered along Yale Street and around First Ward and Woodland Heights reflect this mix vividly: working households, multigenerational arrangements, people commuting well past the Katy Freeway or up the North Freeway, not always back before evening clinics lock the door.
Younger Houstonians (people in their late teens and twenties, a genuinely outsized share of this city) are exactly the ones forming new relationships while also absorbing the highest housing and work pressures. For them, a testing location they can reach without a long drive or a half-day off isn't a convenience; it's what determines whether screening actually fits into a Tuesday that already has no slack in it. The harder part is knowing they're there.
Getting there
Houston scores 10.9/20 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 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.
