Test ID: BAFS    
Bile Acids, Fractionated and Total, Serum

Method Description Describes how the test is performed and provides a method-specific reference

Bile acid concentrations in serum are measured by liquid chromatography-tandem mass spectrometry stable isotope dilution analysis. Serum is mixed with isotopically labeled internal standards of selected bile acids and then subjected to protein precipitation. Sample preparation is semi-automated using a liquid handler. Reverse-phase liquid chromatography is performed using mobile phases to separate free bile acids, their respective tauro- and glyco-conjugates, and 2 bile acid precursors.(Unpublished Mayo method)
