Apolipoprotein B
Apolipoprotein B (Apo B) is the most important transport protein of the "bad" cholesterol particles such as LDL and VLDL. Since each LDL particle carries exactly one Apo B, the Apo B value directly indicates how many atherogenic particles are circulating in the blood. This makes it a very significant marker for the risk of vascular calcifications.
A high Apo B value means an increased risk of heart attack or stroke. Low values, on the other hand, are considered favorable and indicate that fewer harmful particles are present in the blood.
