Lipid Subfraction Analysis

Meaning

Lipid Subfraction Analysis is an advanced diagnostic test that provides a detailed, high-resolution breakdown of the various particle sizes and concentrations of lipoproteins, such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL), in the circulation. This analysis moves beyond the traditional, less informative total cholesterol and basic LDL/HDL numbers. It is a crucial metric in metabolic and hormonal health because the size and number of these particles, not just the total mass of cholesterol, are more accurate indicators of cardiovascular risk and underlying systemic inflammation.
