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.

This application note describes a simple supported liquid extraction method for extraction of estrone and estradiol from human serum. An analytical HPLC-MS/MS method that avoids the use of derivatization or fluoride adduct stabilization (two approaches often used to enhance method sensitivity) is used. High, reproducible analyte recovery and low detection limits (0.001 ng/mL) are achieved.
