This application note describes the extraction of a panel of estrogenic hormones from human serum using EVOLUTE® EXPRESS ABN solid phase extraction plates prior to LC/MS analysis. The simple sample preparation procedure delivers clean extracts and analyte recoveries greater than 90% with RSDs lower than 5% for all analytes. Linearity of greater than 0.99 is achieved for Estrone (E1) and Estradiol (E2) from 5–2000 pg/mL, and 50–20000 pg/mL for Estriol (E3). No derivatization is required, and detection limits are enhanced using a fluorinated mobile phase.
