Two screening methods for the assay of amphetamines and their derivatives have been applied to the same analytical instrument for their evaluation. In addition to an assay at a cut-off of 1000 ?g/l, a new specific reagent was evaluated for an ultra-sensitive assay of amphetamines and 3,4-methylendioxyme-tamphetamine with a cut-off of 300 ?g/l. The assay confirmation was performed using high-performance liquid chromatography and gas chromatography/mass spectrometry techniques. The results were positive for both screening methods, confirming the efficacy of two simultaneous methods with different cut-off levels.
