Sensitivity/PrecisionPerformance around the specific cutoff for each drug was evaluated by testing standard drug solutions diluted in drug-free urine in triplicate on 5 different intervals by3 in-house operators. Drug-free urine was also tested on each interval. The results were interpreted at five minutes.Amphetamine (d-Amphetamine) Cutoff = 300 ng/mLConc.

These 3 operators had at least a high school education, with no formal laboratory testingeducation or laboratory experience, and had some experience running other similar tests to <strong>SURE</strong>-<strong>SCREEN</strong>. The results are summarized in the table below:Amphetamine (d-Amphetamine) Cutoff = 300 ng/mLConc.
