The Apolipoprotein A-1 blood test is used to evaluate survival rate or risk factors for individuals with past heart attacks and peripheral vascular diseases. Apo A-1 recycles cholesterol from the tissues back to the liver for further processing. It keeps the arteries clear of plaque-forming cholesterol.
Exciting new research indicates that low Apolipoprotein A-1 blood levels may be a better indicator of arterial plaque formation (atherosclerosis) than the traditional cholesterol tests for high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL).
Apolipoprotein B is attached to the LDL cholesterol molecule.The measurement of Apo-B is considered to be a better indicator of risk for arterial plaque than LDL cholesterol.
Many doctors also measure the Apo-A1 to Apo-B ratio. A high ratio is cardio- protective … while a low ratio indicates increased risk for heart disease.
A 12 to 14 hour fast is required for this test. Do not eat any food or drink liquids other than water. Take your medications as prescribed. Do not take your supplements the morning of the test.
