calculated serum high density lipoprotein cholesterol level +
serum high density lipoprotein cholesterol to low density lipoprotein cholesterol ratio
A calculated measurement in which the amount of HDL, small-particle lipoproteins that promote transport of cholesterol from extrahepatic tissue to the liver for excretion in the bile, in a specified volume of serum is divided by the amount of LDL, relatively large-particle lipoproteins that transport cholesterol to extrahepatic tissue, in the same sample, and presented as a ratio, fraction, quotient or percentage.
