What are blood lipids? Lipids are fat-like substances found in your blood and body tissues. Your body needs small amounts of lipids to work normally. How are my blood lipids measured? A blood test called a complete lipid profile is done. It is recommended that this test be done after an overnight fast. What happens if my lipids are too high? An excess amount of blood lipids can cause fat deposits in your artery walls, increasing your risk for heart disease.
