LabX ships lab-confirmed at-home drug test kits across St. Louis, Missouri and the surrounding metro — Clayton, Florissant, Chesterfield, 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 St. Louis metro
Every kit ships with prepaid return packaging, so it reaches all of Greater St. Louis — Clayton, Florissant, Chesterfield and beyond. Order online, collect at home, and get results by email. See how mail-in testing works.
Testing in St. Louis — what to know
Recreational marijuana is legal for adults in Missouri, which is exactly why St. Louis-area parents and employers still test — legal for adults is not safe for a teen or acceptable on the job. Full detail on at-home testing in Missouri. Every LabX positive is confirmed by LC-MS/MS, so you get facts rather than the false alarms of a drugstore cup.
Choose your St. Louis test
Order a urine or blood 12-panel screen, add fentanyl, or choose EtG alcohol. Parents start with our home test for parents; St. Louis employers screen staff with the same pre-employment workflow.

Talk to a licensed physician
A drug test result is information, not a diagnosis or medical advice. Review your results, any medications you take and any symptoms with a licensed physician, and call 911 or go to an emergency department if someone is in danger. See our medical disclaimer.
