South Texas Labs is a locally owned and operated drug and alcohol testing facility, founded by siblings Delfina Garcia and Albert Garcia to meet the growing need for reliable testing services in Kingsville.

With 20 years of experience in the medical field, Delfina has worked as a Certified Nurse’s Aide, Medication Aide, and Caseworker in home health care. Albert brings 20 years of expertise in sales, real estate, and insurance, ensuring strong client relations and business operations.

Recognizing the lack of a locally owned testing facility, we established South Texas Labs to provide comprehensive, certified testing services with flexible scheduling, including after-hours and emergency testing—something most hospitals and clinics cannot accommodate.

Our lab is fully insured, and all owners and staff are certified by the appropriate agencies. Additionally, a licensed Medical Review Officer (MRO) oversees all test results, ensuring accuracy and compliance.

At South Texas Labs, we are committed to professional, confidential, and timely testing solutions for individuals and businesses alike.
