Calculated and : Measured. Usually LDL is calculated from total cholesterol, HDL and triglycerides. If triglycerides are higher than 400 then LDL needs to be measured directly for an accurate reading. It is one of the measures of cardiac risk factors.

LDL Not Cholesterol: Actual or directly measured lipoprotein values: LDL always in nmol/l, best <700, HDL in µmol/l, best large-hdl>10. See NMR particle test. Lipoproteins transport all fat molecules within the water outside cells. Cholesterol: a fat molecule made by all animal cells within all cell membranes. Cholesterol is not lipoprotein; lipoproteins carry cholesterol along with all other fat molecules.
