    Abstract

    The effect upon the results of estimating plasma or serum non-esterified fatty acids (N.E.F.A.) assay by different methods of collecting blood samples and subsequent differences in sample storage and time of assay have been studied. Standardization of technique is advised and the use of chilled heparinized tubes, with separation of the sample within one hour of collection and assay on the day of collection is advocated.
