Application Note: Rapid Analysis of 17 Bile Acids in Human Plasma by LC-MS/MS
17 January 2019

Quantitative analysis of bile acids in plasma is critical for diagnosing liver disease as well as assessing drug safety. Accurate reporting can be difficult because of analyte characteristics, matrix effects, and other factors. Here, we establish a rapid, robust, and selective LC-MS/MS method for the analysis of bile acids in human plasma using a Restek Raptor C18 column. One of the significant improvements over other reported methods was the baseline separation of all 17 bile acids in 6 minutes, including three isomer groups.
