This test helps in categorizing lipoprotein as an indicator of cardiac health. It measures the fractions of lipoprotein and is distribution pattern along with the concentration of lipoproteins in the serum. These help in determining the development of coronary artery disease (CAD). This test will determine the density of these lipoprotein fractions as: Chylomicrons Very Low Density Lipoprotein (VLDL), Low Density Lipoprotein and (LDL), High Density Lipoprotein (HDL). An electrophoretic pattern showing the presence of small and densely distributed particles carries three times more risk of developing CAD than the presence of larger particles.
