Plasma and erythrocyte copper, zinc, manganese and magnesium concentrations in Wilson's disease.
Plasma copper was significantly reduced in Wilson's disease with decreased ceruloplasmin levels, while there was no significant difference in erythrocyte copper levels between Wilson's disease and controls. Mean zinc and manganese levels in plasma were increased in Wilson's disease, but these differences were not significant. Mean magnesium level in plasma was normal. The levels of these metals in erythrocytes showed no difference between Wilson's disease and controls. Our results suggest that the abnormal copper level in plasma is not due to the primary metabolic defects, but is probanly due to the level of the binding proteins in plasma to this metal, ceruloplasmin, in Wilson's disease.
