# Apolipoprotein B

> This test measures the amount of Apolipoprotein B (Apo B), a protein found on cholesterol particles that can build up in your arteries. Because every particle that causes plaque buildup carries one Apo B protein, this test provides a more accurate count of the cholesterol that can clog arteries than standard tests alone.
