Abstract
A new method for determining and reporting lipid fatty acids compositions and its use in diagnosing diabetes is disclosed. Adding internal standards, which are true analogs of the fatty acids to be analyzed, to blood serum or plasma samples before performing a gas chromatographic analysis of the fatty acids allows the results of the analysis to be reported in absolute terms as, for example, mg/L, instead of in relative percentages. Reporting the results as absolute concentrations reveals statistically significant differences in levels of various lipid fatty acids between persons having and not having diabetes.
Claims3
A method for determining the likelihood that a patient is at risk for diabetes, comprising the steps of:
- (a) measuring the patient's serum free fatty acid concentration of a fatty acid in absolute weight or absolute moles per volume selected from a group consisting of oleic acid and arachidonic acid;
- (b) comparing the measured concentration to a threshold level of a serum free fatty acid concentration in absolute weight or absolute moles per volume corresponding to the measured fatty acid;
- and,
- (c) determining from the comparison the likelihood that the patient is at risk for diabetes, wherein levels above the threshold level for serum free fatty acid concentration in absolute weight or absolute moles per volume for that fatty acid indicate that the patient is at risk for diabetes.
