Every Service Runs on Donations, Not Copays

South Texas Family Planning and Health accepts donations in place of set fees, meaning the full range of services (testing, treatment, vaccines, and counseling) carries no fixed charge. Sliding-scale pricing backs that up for anyone who does pay, and Medicaid is accepted as well.

Spanish Spoken On-Site, Interpretation Beyond

Spanish is available directly at South Texas Family Planning and Health in Rockport, and interpretation services extend care to other non-English languages, so counseling, consent, and follow-up instructions reach patients in the language they use, not a summarized version of it.

Herpes and Hepatitis B and C Added to the Panel

The testing menu at South Texas Family Planning and Health includes herpes, hepatitis B antibody testing, and a hepatitis C test alongside the core bacterial and viral panel: nine distinct tests in total, each ordered and resulted on-site rather than split across separate referrals.

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.

About Lamar, TX

Lamar's waterfront draws people who've chosen to stay put: boat captains, dock workers, and those who've retired to the bay country build their lives around the rhythms of the water and seasons. That same commitment to staying rooted makes routine health screening practical: people know where they belong and can establish care with providers who know them. STI testing fits naturally into that continuity, especially for the younger adults living here alongside long-term residents and retirees. Confidentiality isn't casual in a town where faces repeat; clinics and testing sites listed on this page understand that discretion anchors their practice.

Testing availability in and around Lamar reflects a community with the means to access care without delay. Whether someone works the water or manages property, whether they're building a career or settled into retirement, screening happens quietly and without fuss: results stay private, and appointments can be scheduled at times that suit a working life. The landscape near Stella Maris Chapel and the Lyndon B Johnson Causeway holds generations of family history. That stability, combined with access to straightforward testing, means young adults here can address sexual health as part of routine care, not crisis.

Confidentiality & consent in Texas

Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

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

Can my partner be treated too? (EPT)

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.
