Phytanic and pristanic acid

Plasma analysis of phytanic acid and pristanic acid is an important tool in the biochemical diagnosis of peroxisomal disorders. In addition to measurement of absolute values, establishing pristanic acid / phytanic acid ratios is of value for the differential diagnosis of Refsum Disease, Rhizomelic Chondrodysplasia Punctata, Peroxisome Deficiency Disorders and isolated peroxisomal ß-Oxidation Deficiencies. Alternatively diagnosis of some of these diseases can be obtained by application of the method to stored blood spots.

Quantification of both acids is usefully combined with the analysis of very long chain fatty acids.
