Ceruloplasmin is a copper-containing protein. This article discusses the test to measure the level of this protein in the clear liquid part of the blood (serum).
A blood sample is needed. For information on how this is done, see: Venipuncture.
No fasting or other preparation is usually needed.
When the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.
Your health care provider may order this test if you have signs or symptoms of a copper metabolism or copper storage disorder.
