What is the definition of a negative drug screen?

A negative drug screen means that the drug test results do not show evidence of illegal or prohibited substances in a student's or applicant's system. This indicates that the person tested either has no detectable levels of the drugs for which the test was designed or, if any substances are detected, the concentrations are below the established threshold or cutoff levels set by the testing standards. These cutoff levels are specifically designed to prevent false positives from incidental or trace exposure to substances.
