Apolipoprotein B (Apo-B)

The apo-B test is used to help assess risk for heart disease, particularly when there is a personal or family history of heart disease.

Apo-B is often used to complement traditional risk assessment tools, such as a lipid panel. Guidelines published by the American Association of Clinical Endocrinologists (AACE) in 2012 support the use of apo-B as an additional risk assessment tool for heart disease.1
