The National Cholesterol Education Program advises that you have your lipids checked at least once every 5 years, starting at age 20. Also, the American Academy of Pediatrics recommends lipid screening for children at risk, such as those with a family history of hyperlipidemia or significant obesity starting between 2 to 8 years old. The National Heart, Lung and Blood Institute recommends routine screening at 9 to 11 years old and again at 17 to 12 years old.
