More on the test...
Serum copper levels or serum cerruloplasmin are useful tests for detecting copper deficiency.Copper is a component of many body proteins; almost all of the body's copper is bound within copper proteins. Unbound (free) copper ions are toxic. About half of ingested copper is absorbed by the body. Excess copper is excreted through bile.
Serum copper may be elevated with infection, inflammation, stress, copper supplementation, oral contraceptives, and pregnancy. Concentrations are 2-3 times normal in the third trimester of pregnancy. Copper may be lowered with corticosteroids, zinc, malnutrition, and malabsorption.
