Our vendor, OHCI, now uses oral mouth swabs, which we ship off via FedEx and get the results in the same amount of time as sending employees to an office in Orem for urine analysis. It's so much easier.
I also collected bids from Victig, Simpliverified, and others if you want more info. There may be vendors at Utah WECon in 2 weeks in Ogden as well.
