Definition - What does random drug testing mean?
Random drug testing is a method of testing for drug use by employees through a process of random selection. These tests are conducted without prior notice to the employee and a systematic selection process is used to assure that each employee has an equal chance of being chosen for testing. Because there is no prior notice as to when this testing will occur, or who will be selected, random drug testing serves both to detect, and deter, drug use.
