ApoB

Apolipoprotein B (ApoB) is a protein that is a key component of lipoproteins, such as LDL ("bad" cholesterol), that transport cholesterol and fats in the blood

Measuring ApoB levels is a powerful tool for assessing cardiovascular disease risk because it can identify individuals at risk even when LDL-cholesterol levels are normal. High ApoB levels increase your risk of heart and blood vessel disease.
