Testing Algorithm

Testing begins with screening assays. If alcohol (ethanol) screen is positive, then the gas chromatography-flame ionization detector confirmation with quantification will be performed at an additional charge. If barbiturates, benzodiazepines, cocaine and metabolites, phencyclidine, or tetrahydrocannabinol metabolite screen is positive, then the gas chromatography-mass spectrometry (GC-MS) confirmation with quantification will be performed at an additional charge. Amphetamines and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry (LC-MS/MS) at an additional charge.

Performing Laboratory

Mayo Clinic Laboratories in Rochester
