This application note describes the extraction of a panel of 19 steroid 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 80% with RSDs lower than 10% for the majority of analytes. Linearity of >0.99 is achieved for all analytes in the range 5–5000 pg/mL.

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.
