Lipid profiling, also known as a lipid panel or lipid profile, is a blood test that measures the levels of specific fats and fatty substances in the blood. These include total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. Lipid profiling is critical for assessing an individual's risk of cardiovascular diseases (CVD) and other metabolic disorders.
