LabX ships lab-confirmed at-home drug test kits across San Antonio, Texas and the surrounding metro — New Braunfels, Schertz, Converse, and everywhere in between. No clinic visit: we mail the kit, you collect and return it prepaid, and our CLIA-certified laboratory confirms the result by LC-MS/MS.
Mail-in drug testing across the San Antonio metro
Every kit ships with prepaid return packaging, so it reaches all of Greater San Antonio — New Braunfels, Schertz, Converse and beyond. Order online, collect at home, and get results by email. See how mail-in testing works.
Testing in San Antonio — what to know
Texas restricts marijuana to limited or low-THC use, so drug testing stays common across the San Antonio metro. More on at-home testing in Texas. Every LabX positive is confirmed by LC-MS/MS, so you get facts rather than the false alarms of a drugstore cup.

Order a 10-panel or 14-panel screen, add fentanyl, or choose EtG alcohol. Parents start with our home test for parents; San Antonio employers screen staff with the same pre-employment workflow.
