This application note describes the extraction of testosterone and androstenedione from female patient serum samples using ISOLUTE® SLE+ (96 well) plates. This method has been optimized to extract testosterone and androstenedione from female clinical serum samples. The method has achieved very low limits of quantitation for testosterone and androstenedione 0.4nmol/L and 0.9nmol/L respectively. The recoveries for both analytes were greater than 90%.

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. MSACL 2016
