Ceruloplasmin

Ceruloplasmin is a protein made in your liver. It stores and carries the mineral copper around your body. Ceruloplasmin carries 65% to 90% of the copper found in blood. Copper is vital to many processes in your body.

A higher-than-normal ceruloplasmin level may be due to: Acute and chronic infections. Cancer (breast or lymphoma) Heart disease, including heart attack.

.

The impaired transport also interferes with incorporation of copper into the copper protein ceruloplasmin, thus decreasing serum levels of ceruloplasmin. Hepatic fibrosis develops, ultimately causing cirrhosis. Copper diffuses out of the liver into the blood, then into other tissues.
