ApoB

Meaning

Apolipoprotein B, or ApoB, is the primary structural protein component of potentially atherogenic lipoproteins, specifically very low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), and low-density lipoproteins (LDL). Measuring ApoB provides a precise count of the total number of atherogenic particles in the circulation, offering a superior clinical metric compared to simply measuring LDL cholesterol alone. Elevated ApoB levels are directly correlated with an increased risk of developing cardiovascular disease, highlighting its importance in comprehensive lipid assessment. This protein is essential for the transport of lipids throughout the body, linking it intrinsically to metabolic and hormonal health.
