Intended Use: Evaluation of Wilson’s disease (hepatolenticular degeneration), liver cirrhosis, and copper deficiency.

Limitations: Oral contraceptives may cause increased values. Because ceruloplasmin is an acute phase reactant, use caution in interpreting results where inflammation or infection are present.

Clinical Significance: Ordered with a blood or urine copper test, ceruloplasmin helps in the diagnosis of Wilson’s disease.
