Types Of Drug Testing

There are about five primary types of drug testing that are considered biologically viable proof of illegal or narcotic substances in the body. These are urine, blood, hair, saliva, and sweat. The urine test is perhaps the most common, as it is inexpensive and is less intrusive to the person than most of the other tests.

Most types of drug testing screen the body for 5 categories of drugs (or, as they are called, the "NIDA 5"). These five categories must be tested, for example, in federally required tests in addition to hiring and employing commercial class drivers. The five substance categories are cocaine (includes crack and benzoylecognine), amphetamines (including methamphetamines and speed), cannabinoids (marijuana, hash), opiates (opium, morphine, and heroin), and phencyclidine (or PCP).

Other Types of Drug Testing

There are some so-called "expanded" tests which can encompass lesser-known but still prevalent societal drugs. These can include barbituates, alcohol, Ecstasy, valium, and vicodin. If an employee passes a drug test, but the employer still has reason to suspect that he or she might be high on the job, then these expanded tests could be used.

All of these drug testing types do not mean anything unless you take the time to sit down and find a way towards understanding drug test results. Take the moment to see if the drugs in the system were truly enough to impair the employee or not. No matter what, speak candidly to your employee regarding the data you receive, and allow him to explain himself should he feel there's a reason to.
