Untargeted metabolomics

Definition

Untargeted metabolomics is an analytical approach that aims to comprehensively identify and quantify all metabolites within a biological sample without prior knowledge of which specific metabolites are present. This method allows for the discovery of novel biomarkers, as it analyzes the entire metabolome, facilitating insights into metabolic pathways and biological processes.
