The present invention provides a method for diagnosing a disease or disorder selected from the group consisting of insulin resistance, a metabolic disorder, diabetes and pre-diabetes in a subject. The method comprises the step of determining the level of a compound represented by structural formula (VI): or a salt thereof. Compositions and method of making thereof are also described.

Diagnostic methods, therapeutic agents and uses thereof

A method for determining the amount of one or more analytes in a sample by mass spectrometry is described. The one or more analytes are selected from the group consisting of alpha-hydroxybutyrate (2-HB), linoleoyl LPC (LGPC), oleic acid, 3-hydroxybutyrate (3-HB), 4-methyl-2-oxopentanoate (4-MOP), pantothenate, and serine. The method includes a) subjecting the sample to an ionization source under conditions suitable to produce one or more ions detectable by mass spectrometry from each of the one or more of the analytes, wherein the analytes are not derivatized prior to ionization; b) measuring, by tandem mass spectrometry, the amount of the one or more ions from each of the one or more analytes; and c) using the measured amount of the one or more ions to determine the amount of each of the one or more analytes in the sample.

Mass spectrometry method for detection and quantitation of metabolites

A method for determining in a sample, by mass spectrometry, the presence, absence, or amount of one or more analytes is described herein. The run time is less than six minutes. The method includes subjecting the sample to an ionization source under conditions suitable to produce one or more ions detectable by mass spectrometry from each of the one or more analytes, wherein the one or more analytes are derivatized prior to ionization; measuring, in a single injection, by mass spectrometry, the amount of the one or more ions from each of the one or more analytes; and using the measured amount of the one or more ions to determine the amount of each of the one or more analytes in the sample.

Mass spectrometry assay method for detection and quantitation of organic acid metabolites

The present invention provides a method for diagnosing a disease or disorder selected from the group consisting of insulin resistance, a metabolic disorder, diabetes and pre-diabetes in a subject. The method comprises the step of determining the level of a compound represented by structural formula (VI): or a salt thereof. Compositions and method of making thereof are also described. 

A method of extracting and measuring one or more biochemicals from a biological sample, comprises immersing the biological sample in an organic solvent, whereby one or more biochemicals present in the biological sample are extracted into the organic solvent; separating the biological sample from the free organic solvent; and measuring the level(s) of the one or more biochemicals extracted into the organic solvent, wherein the biological sample remains analyzable by histological analysis.
