Modification of the Fiske and SubbaRow method for total phospholipid in serum

Abstract

Many of the difficulties encountered in the original Fiske and SubbaRow method for estimating serum phospholid were corrected through the use of vanadium pentoxide, a catalyst used in sample digestion, and through other minor modifications. Results obtained by the modified method agree well with those obtained by three other established phospholipid procedures. The greatly improved speed, simplicity, accuracy, and precision now makes the modified Fiske and SubbaRow method ideal for clinical or research use.
