WHAT IS CERULOPLASMIN (CP) TEST?
Ceruloplasmin is an alpha2-globulin transport protein that transports copper and aids in mobilising iron stores. It is an acute-phase reactant that becomes elevated during stress, pregnancy, and infection. This test is most often used to aid diagnosis of Wilson’s disease, in which subnormal quantities of ceruloplasmin are manufactured by the liver. The resulting tissue deposition of copper causes brain and liver damage.
