Fredrickson Classification[edit | edit source]

Fredrickson is best known for developing the Fredrickson classification of hyperlipidemia, a system that categorizes lipid disorders based on the pattern of lipoproteins in the blood. This classification system, also known as the World Health Organization (WHO) classification, is used worldwide to diagnose and manage hyperlipidemia.

The Fredrickson classification includes five types of hyperlipidemia:

  • Type I: Familial hyperchylomicronemia
  • Type II: Familial hypercholesterolemia
 * Type IIa: Elevated LDL
 * Type IIb: Elevated LDL and VLDL
  • Type III: Familial dysbetalipoproteinemia
  • Type IV: Familial hypertriglyceridemia
  • Type V: Mixed hyperlipidemia

Each type is associated with different lipid profiles and risks for cardiovascular disease.
