Term:
blood intermediate-density lipoprotein phospholipid measurement test
A laboratory test which measures the amount of phospholipid (phosphorus-containing lipids composed mainly of fatty acids, a phosphate group, and a simple organic molecule) found in the intermediate-density lipoprotein (IDL) fraction of blood. IDL are relatively large lipoprotein particles (complexes that consist of a protein layer surrounding a core of lipids) formed by degredation of very low density lipoproteins (VLDL) particles and thus having a size intermediate between those of VLDL and low density lipoproteins (diameter approximately 25-50 nm).
