| Additional information | To convert µg/L to µmol/L (SI units), multiply by 0.0157. Copper is an essential element that is a cofactor of many enzymes. Copper metabolism is disturbed in Wilson's disease, Menkes disease, primary biliary cirrhosis, and Indian childhood cirrhosis. Urinary copper concentrations are also useful to monitor patients on chelation therapy. |
