When to get tested?
When you have jaundice, fatigue, abdominal pain, behavioural changes, tremors, or other symptoms that your doctor thinks may be due to Wilson’s disease or, rarely, to copper deficiency or excess; at intervals when you are being treated for a copper-related condition

Sample required?
A blood sample drawn from a vein in your arm and/or a 24-hour urine sample; sometimes a liver biopsy sample
