Apolipoprotein B (Apo-B) is a protein found on the harmful cholesterol-carrying particles in your blood. Because each such particle carries one Apo-B, measuring it gives a good count of these particles and your heart risk. The Apo-B blood test measures the level of this protein. It helps assess the risk of heart disease, sometimes more precisely than standard cholesterol tests alone.
