The Arizona Department of Public Safety Toxicology Unit recently changed its analytical workflow for the testing of drugs in blood. This new workflow will drastically improve turnaround times and increase the number of drugs the laboratory is able to identify. These improvements have been made possible with the implementation of new liquid chromatography quadrupole time-of-flight mass spectrometry instruments (LC-QTOF). This presentation will cover the benefits of the new workflow, how the LC-QTOF works, and the meaning of the analytical results.
