Clinical Info	It is used, along with serum ceruloplasmin and urine copper, to test for Wilson's disease and (more often) in monitoring the nutritional adequacy of parenteral or enteral nutrition, especially when copper deficiency may be suspected because of ongoing gastrointestinal losses of the element (see table). The test is done in suspected copper toxicity in premature infants when they are acutely ill and may not be able to assimilate the copper in their prescribed nutrition; in acute copper intoxications; or in “Indian childhood cirrhosis,” an illness not limited to Indian children.
