Apolipoprotein B Test

The Apolipoprotein B (Apo B) test is a blood test that measures the levels of apolipoprotein B in the bloodstream. Apolipoprotein B is a protein component of low-density lipoprotein (LDL) cholesterol, often referred to as "bad cholesterol." LDL cholesterol plays a significant role in transporting cholesterol to tissues and cells throughout the body. This test is used to assess LDL cholesterol function and predict cardiovascular risk. Higher levels of Apo B are associated with an increased risk of atherosclerosis and heart disease, as it reflects the concentration of LDL particles in the blood. Elevated Apo B levels may indicate an increased likelihood of plaque build-up in the arteries, leading to narrowing and potential blockages.
