Drug Test Cut off Levels

Cut-off level is a medication testing concept that describes this stage under a drug test is referred to as negative and above that a drug test is called positive. By a stage that will optimize medication detection whilst maintaining minimal positive results, the cut-off is determined for drug screening. It’s very important to emphasize at this point that a negative impact does’t automatically imply a sample is drug free, simply the sum of concentration of any substance it may include is under the specified cut-off.
