	In roadside testing (police), safety-sensitive workplace testing (transport, mining, construction, manufacturing, energy, etc.) and various departments, forces and services, EyeCheck and oral fluid offers several advantages over urine, whereas urine offers a longer track record of the subject/employee. As oral fluid is a lab. test the best system of today is EyeCheck followed by a urine test.
