Measurement of the amount of cholesterol, a eukaryotic sterol that in higher animals is the precursor of bile acids and steroid hormones and a key constituent of cell membranes, carried in very low-density lipoprotein (VLDL) molecules in a specified volume of blood, the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. VLDL constitute a class of large (e.g. approximately 30-80 nm in diameter) lipoprotein particles, complex molecules that consist of a protein membrane surrounding a core of lipids. The VLDL class of lipoproteins has a density between 0.95 and 1.006 g/ml.
