This condition is diagnosed with blood tests. These tests measure the levels of triglycerides in the blood. 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.

- LDL (bad cholesterol)
- HDL (good cholesterol)
Your doctor may recommend more frequent or earlier testing if you have a:
- Family history of hyperlipidemia
- Risk factor or disease that may cause hyperlipidemia
- Complication that may result from hyperlipidemia
