Lipemia Index


The number reported under Lipemia measures the turbidity of the sample in terms of concentrations of lipid in an emulsion of fat. This correlates weakly to the triglyceride concentration in the sample.

Cornell University provides guidelines on how turbidity (usually due to lipemia) affects sample results, e.g. a lipemic index of >100 may (not always) falsely decrease electrolyte concentrations. These guidelines are derived from manafacturer's recommendations and is based on data from spiking human samples with a fat emulsion (Intralipid®). These values may not apply to samples from animals and there may be species differences. These guidelines should always be used in conjunction with clinical signs and knowledge of the underlying disease processes as guides for interpreting laboratory data and determining the accuracy of reported laboratory results.
