Apolipoprotein A1 Test

The apolipoprotein A1 (Apo A1) test is a blood test that measures the levels of apolipoprotein A1 in the bloodstream. Apolipoprotein A1 is a protein component of high-density lipoprotein (HDL) cholesterol, commonly known as "good cholesterol." HDL cholesterol plays a crucial role in transporting cholesterol away from the arteries and back to the liver for excretion, helping to prevent the build-up of plaque and reducing the risk of cardiovascular diseases. The Apo A1 test is used to assess HDL cholesterol function and predict cardiovascular risk. Higher levels of Apo A1 are associated with a reduced risk of heart disease, while low levels may indicate an increased risk.
