Apolipoprotein B


Apolipoprotein B, or ApoB is the primary apolipoprotein of low-density lipoproteins (LDL or bad cholesterol). It is responsible for carrying cholesterol to tissues.

What might a high result mean?

High levels of Apolipoprotein B can lead to plaques that cause vascular disease, or atherosclerosis, which increases the risk of heart disease. There is evidence that levels of apo B are a better indicator of heart disease risk than total cholesterol or LDL cholesterol.
