Acquired intoxication is the result of consumption or absorption of excess copper (for example, consumption of foods or beverages that have long been stored in copper containers).
Hereditary copper intoxication (Wilson's disease) leads to accumulation of copper in the liver and other organs. Hepatic or neurologic symptoms develop. The diagnosis is based on a low serum level of ceruloplasmin, a high level of copper excretion in the urine, and sometimes liver biopsy results. Treatment consists in chelation, usually with penicillamine.
