Test method


A new and simplified method for the analysis of fatty acids profile in the blood without lipid extraction has been discovered. This new method, that uses drops of blood collected from a fingertip (see picture below), has been compared to the conventional method of lipid analysis based on withdrawal of venous blood.


   


Full linearity in the gas chromatographic response of 11 individual fatty acids are maintained from C14 to C24 peaks with increasing sample size in the range 15-75 mcg. This new method for the analysis of fatty acids profile in the blood is approved for nutritional studies.

The fatty acids profile of blood lipids reflects dietary fat intake, and studies have shown that this profile is strongly related to health status. This is because the blood lipid profile represents the types of fats your body has to build into all cells and tissues, including cell membranes.


      


Thus, this new method for the analysis of fatty acids profile in the blood is applicable to nutritional studies. The 11 fatty acids are : Palmitic acid(PA), Stearic acid(SA), Oleic acid(OA), Linoleic(LA), Alpha-Linolenic acid(ALA), Gamma-linolenic acid(GLA), dihomoGamma-linolenic acid(DHGLA), Arachidonic acid(AA), Eicosapentaenoic acid(EPA), Docosapentaenoic acid(DPA), Docosahexaenoic acid(DHA).
