Background: γ-hydroxybutyric acid (GHB), notorious as a club- and date-rape drug, was quantified in dried blood spots (DBS) by punching out a disc, followed by on-spot derivatization and analysis by GCMS. Results: A homogenous distribution in DBS was demonstrated and accurate results were obtained when analyzing a disc punched out from a 2035 µl spot, regardless the hematocrit of the blood sample. Validation based on US FDA and European Medicines Agency guidelines was performed, with a calibration range covering 2100 µg/ml. Conclusion: A sensitive GCMS method for GHB analysis in DBS was successfully optimized and validated. The successful analysis of DBS collected from GHB abusers suggests the routine applicability of the DBS sampling technique for GHB analysis in toxicological cases. |
