DRUG CUT-OFF LEVELS
What are Drug Cutoff Levels?
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.
In a drug test, a negative result is defined as a specimen that does not indicate a level of drugs at, or above, the specified concentration of a drug. That specified concentration used is called the cut-off level. A specimen that contains drugs at or above the determined cut-off level is positive.
If you are interested in locating the cut-off level for your product, Ovus Medical provides information with each shipment. Each package comes with a Cut-off level list located on the second page of the pamphlet shipped.
