title: [The determination of clozapine in blood and urine by gas chromatography-mass spectrometry].
abstract: A method for measuring closapine in the blood and urine by gas chromatography-mass spectrometry as a trifluoroacetic derivative is proposed. The threshold level for closapine detection is 25 ng/ml in the blood and 30 ng/ml in the urine. Calibration curves are linear in the range 0.025-5 mcg/ml for the blood and 0.03-50 mcg/ml for the urine. The method can be used in forensic chemical and clinical toxicological analysis.
