Apolipoprotein B100 (apoB100) is the primary protein in low-density lipoprotein (LDL) cholesterol. The apoB100 test measures the amount of this type of cholesterol in the blood. LDL is often referred to as “bad” cholesterol because high levels of it can damage the heart and blood vessels.
This test is to evaluate your risk of developing cardiovascular disease (CVD); sometimes to help monitor treatment for high cholesterol or to help diagnose a rare inherited apolipoprotein B (apo B) deficiency
The normal range for apoB is 40-125 mg/dL. Usually less than 100 mg/dL is considered desirable in low or intermediate risk individuals. Less than 80 mg/dL is desirable in high risk individuals, such as those with cardiovascular disease or diabetes.
