When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away.
Why the Test is Performed
Ceruloplasmin is made in the liver. Ceruloplasmin stores and transports copper in the blood to parts of the body that need it.
Your health care provider may order this test if you have signs or symptoms of a copper metabolism or copper storage disorder.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples. Talk to your provider about the meaning of your specific test results.
What Abnormal Results Mean
Lower-than-normal ceruloplasmin levels may be due to:
