Lipoprotein Particle Numbers Explained: Why ApoB Matters
Traditional cholesterol tests measure the amount of cholesterol circulating in the blood. However, many cardiologists now focus on lipoprotein particle numbers.
These particles transport cholesterol through the bloodstream and play a central role in cardiovascular health.
Why Particle Number Matters
Cardiovascular disease remains Australia’s leading cause of death.
According to the Australian Institute of Health and Welfare, cardiovascular disease accounts for approximately one in four deaths nationwide.
What Lipoprotein Particles Are
Lipoproteins are particles that transport fats through the bloodstream.
Each particle capable of entering the artery wall carries one molecule of Apolipoprotein B (ApoB).
Expert Insight
Professor Allan Sniderman, a leading lipid researcher at McGill University, has explained: “ApoB is the most accurate way to measure the number of atherogenic particles in circulation.”
what ApoB Is important
Because each particle contains one ApoB molecule, measuring ApoB provides a direct count of potentially atherogenic lipoproteins.
Why Context Matters
ApoB is often interpreted alongside:
