Recreational marijuana use is currently legal in eleven U.S. states. Fourteen additional states have decriminalized marijuana, but have not legalized it. It is increasingly important for laboratories to develop accurate testing methods for THC, and its related compounds, in biological matrices of those that may be driving or committing crimes under the influence of marijuana. Biotage provides simple and effective sample prep protocols for cleanup of blood, urine, and oral fluid samples that produce reliable results, and are automation compatible.

This poster demonstrates a rapid and reliable sample preparation method using Supported Liquid Extraction (ISOLUTE SLE+) to extract a suite of 30 hormone analytes from a hydrolyzed urine matrix. Single injection analysis by LC-MS/MS shows that matrix effects are eliminated by the ISOLUTE SLE+ protocol and that analyte recovery and sensitivity have excellent clinical utility.

In all areas of analytical laboratory testing it is vital to ensure proper quality measures are in place to reduce or eliminate cross contamination between samples, which could result in false positive and/or false negative results. In many cases sample carryover in the LC/MS system is checked early on in the method development process. However, one area that can often be overlooked the sample preparation stage. This involves all aspects including pipetting, sample transfer, extraction protocol, evaporation and mixing steps. This poster examines various stages of the sample preparation process to determine the potential for cross contamination and present approaches to minimize and or eliminate the effect. This is demonstrated via a series of dye experiments combined with analyte testing using LC-MS/MS.
