Aim: The objective of the study was to check if gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) is a suitable method to differentiate between endogenous and exogenous GHB in urine. Methods: In the presented study, a controlled and monitored administration of 2.25 g GHB (Xyrem) to one participant was carried out. Spot urine samples were collected once before administration and at different time intervals after the intake (2 h; 4 h; 6 h; 8 h; 12 h; 24 h; 48 h and 72 h… CONTINUE READING
