Ceruloplasmin

Understanding Ceruloplasmin

Ceruloplasmin is a protein produced by the liver that helps transport and store copper through the blood. About 65% to 90% of the copper in the blood is carried by ceruloplasmin. Copper is important for many body functions, like building strong bones and making skin pigment (melanin).

Normally, the liver extracts copper from the blood and binds it to the ceruloplasmin protein. The ceruloplasmin is then released into the blood, transporting copper to various body parts. The Ceruloplasmin test provides important ins...

What does Ceruloplasmin measure?

The Ceruloplasmin test is a blood test that measures the level of ceruloplasmin, a copper-binding protein. This test is done to evaluate copper metabolism in the body. It helps diagnose conditions like Wilson’s disease, a genetic disorder that can lead to excess storage of copper in the eyes, liver, brain, and other organs.
