APOLIPOPROTEIN - B (APO-B) test is recommend to diagnose a rare hereditary deficiency called Apolipoprotein B (APO-B) deficiency. Besides that, this test also helps to monitorthe risk of developing Cardiovascular Disease (CVD) and check the progress of an ongoing treatment for high cholesterol.
Apolipoprotein B is also known as Apolipoprotein B 100 or APO-B. It is a type of protein which is the main component of lipoproteins. This protein is responsible for the metabolism of lipids.
There are two main components of liprotein called very-low-density lipoprotein and low-density lipoprotein. Hence this test measures the total amount of Apolipoprotein B present in the blood.
Apolipoprotein gets dissolved with lipids and flows into the bloodstream. While most of the lipoproteins that are present in the body are cholesterol and triglyceride.
On the other hand, there are chylomicrons which are considered as particles of lipoprotein. The role of this lipoprotein is to transfer dietary lipids from the digestive tract to tissues of liver through the bloodstream.
The doctor prescribes this test if you have a family history of heart disease or is at the risk of developing cardiovascular disease. Or if your doctor suspects you of suffering from the rare hereditary disease.
