LabX ships lab-confirmed at-home drug test kits anywhere in Missouri — from Kansas City, St. Louis, Springfield to every town in between. There is no clinic visit: we mail the kit, you collect the sample and return it in prepaid packaging, and our CLIA-certified laboratory confirms the result by LC-MS/MS.
Mail-in drug testing across Missouri

Order online, collect at home, and get results by email. See how mail-in testing works, or read the full at-home drug test walkthrough.
Missouri marijuana laws & why testing still matters
Recreational marijuana is legal for adults in Missouri — which is exactly why so many parents, employers, and individuals still test. Legal for adults does not mean safe for a teen, permitted on the job, or acceptable in a safety-sensitive role. A lab-confirmed test with LC-MS/MS confirmation gives you facts, not guesses.
Choose your Missouri test
Order a 10-panel or 14-panel screen, add fentanyl, or choose EtG alcohol testing. Parents can start with our home test for parents; Missouri employers can screen remote staff with the same pre-employment workflow.
