Methodology
Initial presumptive testing by immunoassay at the following testing thresholds: amphetamines, 50 ng/mL; barbiturates, 0.1 ?g/mL; benzodiazepines, 20 ng/mL; cocaine metabolite, 25 ng/mL; methadone, 25 ng/mL; opiates, 5 ng/mL; phencyclidine (PCP), 8 ng/mL; propoxyphene, 50 ng/mL; tetrahydrocannabinol (THC), 5 ng/mL; presumptive positives confirmed to limit of quantitation by definitive chromatography mass spectrometry (GC/MS or LC/MS-MS). Initial presumptive testing for ethanol by enzymatic assay at a testing threshold of 0.020 gm/dL; presumptive positives confirmed by gas chromatography (GC).
