| Research Abstract |
We have developed a rapid procedure for simultaneous extraction of a wide range of acidic and basic drugs from whole blood samples for reliable semi-quantitative drug screening by GC-MS. To extract the wide range of drugs, the partition/extraction procedure used for the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) method was selected at the initial step and the protein-lipid removal filter cartridge (Captiva ND Lipids) was found to be useful to remove interference compounds to obtain clean extracts as the second step to be connected to GC-MS screening using the NAGINATA software with our constructed calibration-locking database. We also examined the applicability of our established method in an actual forensic case. The established preparation procedure was applied to tissue samples with some modification, and it was also suitable for LC-MS/MS screening.
