Using MS1-based precursor ion quantification, the method demonstrated excellent analytical performance with linearity (R\u00b2 &gt; 0.99), accuracy (84 %-131 %), and precision (1 %-17 % relative standard deviation (RSD)). Although LC-QTOF\u2011MSE sensitivity is at least nine-fold lower than LC-triple quadrupole MS with multiple reaction monitoring, it remains adequate for quantifying urinary metabolites, particularly those that fragment poorly or yield low\u2011intensity product ions. For post\u2011targeted screening and untargeted profiling, an in\u2011house reference library (the Siriraj Metabolomics Data Warehouse, SiMD), comprising 174 curated metabolite standards, was integrated into the workflow to enhance metabolite identification confidence. The official website for SiMD can be accessed at https:\/\/si-simd.com\/. To demonstrate the method&#8217;s utility, 11 amino and organic acids were quantified in urine samples from 100 healthy individuals. Four compounds-L-methionine, L-histidine, L-tryptophan, and trans-ferulic acid-were significantly higher levels in females (P &lt; 0.05), likely reflecting sex-specific physiological or dietary intake differences. Post\u2011targeted screening identified 29 additional metabolites and assigned them to level 1 (m\/z, RT, isotope pattern, and MS\/MS spectra matched to reference standards) based on the Metabolomics Standards Initiative guidelines. Untargeted retrospective profiling revealed level 1 seven metabolites, including ribitol, creatine, glucuronic acid, trans-ferulic acid, succinic acid, dimethylglycine, and 3-hydroxyphenylacetic acid related to sex variation (VIP &gt; 1.5). In summary, the LC-QTOF-MSE method coupled with SiMD provides a robust and comprehensive workflow for metabolomics analysis. It enables reliable target quantification and enhances confidence in metabolite identification while also reducing sample and instrumental demands. These features make it particularly well-suited for clinical metabolomics studies.<\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/40703097\/\">https:\/\/pubmed.ncbi.nlm.nih.gov\/40703097\/<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Abstract This study presents the development and validation of a liquid chromatography-quadrupole-time-of-flight mass spectrometry method with data-independent acquisition (LC-QTOF-MSE) for targeted quantification, post-targeted screening, and untargeted metabolite profiling.
