Clinical Application
Investigation of suspected Wilson's disease, e.g where ALT is persistently elevated. Use in conjunction with serum measurement of caeruloplasmin. Urine copper excretion may also need to be measured if serum copper/caeruloplasmin is abnormal or equivocal.
Acute inflammatory response causes gradual increase in copper concentration due to induction of caeruloplasmin synthesis. Consider appropriateness of request if CRP is significantly elevated (e.g. if CRP 100-200, there may be a 30% increase in serum copper concentration).
Copper results should be interpreted alongside albumin and CRP results.
