Measures apolipoprotein B (ApoB), the main protein on LDL and other 'bad' cholesterol particles. Each harmful particle carries one ApoB.
Counts the number of atherogenic particles and can predict heart risk better than LDL alone, especially in diabetes, high triglycerides or metabolic syndrome.
Adults over 30, people with high BP, diabetes, obesity, smoking or a family history of heart disease; chest pain or breathlessness (seek urgent care).
No fasting needed.
