What Is a Cut-Off Level?
The cut-off level is a drug testing concept that refers to that point under which a drug test is called negative and above which a drug test is called positive. For drug screening, the cut-off is determined at a point that will optimize drug detection while maintaining minimum false-positive results. It is important to emphasize at this point that a negative result does not mean that a sample is drug-free, only that the level of concentration of any substance that it may contain is below the defined cut-off.
