Lipoprotein Fractionation
Lipoprotein Fractionation is a test that measures the levels of different types of lipoproteins in the blood, including LDL, HDL, and VLDL. This test can help assess the risk of heart disease.
iollo markers that associate with Lipoprotein Fractionation
Cholesteryl ester 14:0
Cholesteryl esters are components of lipoproteins. The fatty acid composition of cholesteryl esters, such as 14:0 (myristic acid), can influence lipoprotein particle size and density.References
