Ceruloplasmin
Ceruloplasmin is the main copper-carrying protein in blood and functions as a ferroxidase that supports iron loading onto transferrin. Low levels are classic for Wilson disease, an inherited disorder of copper accumulation, and can also occur in severe malnutrition or liver failure. As an acute phase reactant, it can be transiently elevated during inflammation, obscuring copper deficiency.

What is Ceruloplasmin?
Ceruloplasmin is the main copper-carrying protein in blood and functions as a ferroxidase that supports iron loading onto transferrin. Low levels are classic for Wilson disease, an inherited disorder of copper accumulation, and can also occur in severe malnutrition or liver failure. As an acute phase reactant, it can be transiently elevated during inflammation, obscuring copper deficiency.
Why It Matters
Primary copper transport protein. Low levels indicate Wilson disease (copper accumulation). Also an acute phase reactant elevated in inflammation. Important for iron metabolism.
