Lincoln Avenue <br />West Allis, Wl 53227-0901 <br />800-877-7016 <br />A5228 999 <br />a <br />a <br />lnitial Screen <br />All urine specimens will be initially tested for the use of controlled <br />substances by an immunoassay screen, which will eliminate negative <br />urine specimens from further consideration. Any positive test results in <br />an initial test will be subject to confirmation through an additional, more <br />precise and accurate testing methodology. <br />The cut-off levels set forth below will be used for the initial screening of <br />specimens to determine whether they are negative for the following <br />drugs: <br />Marijuana metabolites - 50 ng/ml <br />Cocaine metabolites - 300 ng/ml <br />Opiate metabolites - 2000 ng/ml <br />Phencyclidine - 25 ng/ml <br />Amphetamines - 1,000 ng/ml <br />These cutoff levels are subject to change by the Department of Health <br />and Human Services as advances in technology or other <br />considerations warrant identification of these substances at other <br />concentrations. <br />Confirmatory Tests <br />Any urine specimen identified as positive on the initial test screen will <br />be confirmed by a second analytical procedure independent from the <br />initial test and which uses a different chemical technique and <br />procedure. Gas chromatography/mass spectrometry will be used to <br />confirm initial positive test results. <br />The cut-off levels set forth below will be used to establish the <br />existence of a "confirmed positive" test result: <br />Marijuana metabolites - 15 ng/ml <br />(delta 9tetrahyd rocan nabinol-9- <br />carboxylic acid) <br />Cocaine metabolites - 150 ng/ml <br />(benzoylecgonine) <br />32
