EVALUATION OF NON-CERULOPLASMIN COPPER BY PROTEIN SPECIATION (NCC-SP) AND 24-HOUR URINARY COPPER EXCRETION (UCE) FOR MONITORING CHELATOR TREATMENT IN PATIENTS WITH WILSON DISEASE.
<div><p><strong><b>Background:</strong> </b>NCC and UCE are recommended for treatment monitoring in Wilson Disease (WD)(1). NCC is assumed to reflect the bioavailable copper (Cu) in plasma and is in equilibrium with the pool of stored Cu. UCE reflects body stores of Cu and is also influenced by the cupriuretic effect of therapy. Current methods to estimate NCC are flawed.
