Common use of Confirmatory Test Clause in Contracts

Confirmatory Test. All specimens identified as positive on the initial test shall be confirmed using gas chromatography/mass spectrometry (GC/MS) techniques at the cutoff values listed. The following cutoff levels shall be used to confirm the presence of drugs or drug metabolites: Substance Confirmatory Test Level (ng/mL) Marijuana Metabolites (12) 15 Cocaine Metabolites (2) 100 Oxycodone/Oxymorphone Opiates: 100 Morphine (3) 2000 6-Acetylmorphine 10 Codeine (3) 2000 Phencyclidine 25 Amphetamines: Amphetamine/ Methamphetamine (4) 250 MDMA(4) /MDA/MDEA (5) 250 (1) For grouped analytes (i.e. two or more analytes that are in the same drug class and have the same initial test cutoff): (2) An immunoassay must be calibrated with the target analyte, A-9- tetrahydrocannabino 1-9-carboxylic acid (THCA). (3) Alternate technology (THCA and Benzoylecgonine): When using an alternate technology initial test for the specific target analytes of THCA and Benzoylecgonine, the laboratory must use the same cutoff for the initial and confirmatory tests (i.e., 15ng/mL for THCA and 100ng/mL for Benzoylecgonine).
