Here we evaluate an LC-MS/MS method used to measure serum tes tos terone and androstenedione enabling investigation of metabolic dysfunction for clinical research purposes. An analytically selective method was developed using a mixed-mode Solid Phase Extraction (SPE) sorbent in 96-well plate μElution format. The use of this μElution chemistry provides precise and accurate measurement of testosterone and androstenedione to high analytical sensitivity.
