On-site DOT and non-DOT drug testing for San Marcos employers. Our certified collector comes to your location — same-day available, 7 days a week.
This San Marcos page is built for employers and organizations that need a collector to come to them instead of sending staff across town. We regularly help businesses near North County business parks, schools, and contractor routes when they need a pre-employment screen, same-day post-accident collection, random testing support, or a scheduled on-site collection day. Mobile service reduces downtime and keeps your hiring or incident workflow moving.
In San Marcos, common buyers of mobile drug testing include manufacturing support, staffing firms, schools, restoration companies, and commercial contractors. Many of these employers do not want the delay and lost labor hours that come with clinic travel. A mobile collector can meet at the office, yard, job site, warehouse, sober living home, or another approved collection location anywhere in the service area.
We also coordinate well with nearby areas including Escondido, Vista, Carlsbad, and Oceanside, so companies with multiple sites can use one local number for scheduling across San Diego County. For DOT collections, we follow urine collection procedures under 49 CFR Part 40. For non-DOT testing, we can help with rapid screens, random programs, and same-day response when timing matters.
