The QTrap liquid chromatography-tandem mass spectrometry (LC-MS-MS) by Applied Biosystems was investigated as an adjund to enzyme immunoassay (EIA) for the rapid detection of drugs in blood. Thus, a procedure used to identify drugs in whole blood by EIA was extended to LC-MS-MS analysis. A multiple reaction monitoring (MRM) database of over 100 drugs was constructed to analyze for those drugs commonly observed in postmortem toxicology cases. The QTrap method provided for a scan time of only 2.8 s to produce both an MRM and an enhanced product ion scan. Various validation and developmental steps of the method are presented, as well as a concordance study as a final means of validation. This study was conducted to compare the effectiveness of the QTrap versus conventional extraction methods and gas chromatography-MS for the identification of drugs in 95 postmortem samples. The more than 400 drug results in this study showed 100% concordance between the two techniques.
