LabX ships lab-confirmed at-home drug test kits across San Francisco, California and the surrounding metro — Oakland, Daly City, South San Francisco, 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 Francisco metro
Every kit ships with prepaid return packaging, so it reaches all of Greater San Francisco — Oakland, Daly City, South San Francisco and beyond. Order online, collect at home, and get results by email. See how mail-in testing works.
Testing in San Francisco — what to know
Recreational marijuana is legal for adults in California, which is exactly why San Francisco-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 California. Every LabX positive is confirmed by LC-MS/MS, so you get facts rather than the false alarms of a drugstore cup.
Choose your San Francisco test
Order a 10-panel or 14-panel screen, add fentanyl, or choose EtG alcohol. Parents start with our home test for parents; San Francisco employers screen staff with the same pre-employment workflow.
