Abstract

The extraction and untargeted UHPLC-HRMS analysis of endogenous steroids in serum samples is described in this protocol. The employed full-scan acquisition mode provides the adequate sensitivity to highlight the main endogenous steroids present in blood, including mineralocorticoids, progestogens, and androgens. Technical aspects for both chromatography and mass spectrometry are discussed in detail, together with a proposition of setup for sample sequence and data analysis. Furthermore, general comments are given to help the assessment of data quality and system performance.
