A multi drug panel screen test became mandatory for Federal Employees during President Reagan's term as President (1981-1989) for specific DOT (Department of Transportation) regulations. Multi drug screening tests are used to detect any illegal drugs in a person's system. Depending on what type of, or level of, drug screening is required, there are also different types of drug screening tests.
Most companies use a 5 panel drug screen. The 5 panel drug screen can either be administered by an outside company or can be purchased to use at the workplace by an administrator to follow the steps for the test and to record the results. Drugs that can be detected by a 5 panel drug screen can include the hallucinogenic drug PCP, marijuana, cocaine, meth amphetamines and opiates. The 5 panel drug screen is the most commonly used for regular workplace drug screens. The 5 panel drug screens are usually tested with urine samples, saliva and, in some cases, blood tests. They will either be in the form of test strips or cups with lids to hold the urine or saliva.
