LOINC description : A free copper level is calculated based on the difference between total copper and
ceruloplasmin measurements, where the ceruloplasmin level represents the bound portion
of circulating copper. In patients with Wilson's disease that is pre-symptomatic or
adequately controlled, the free copper level is within normal range, but in symptomatic
patients, it is typically elevated. Increasing free copper levels in a patient with
previously normal levels may indicate a change in compliance with therapy or a growth
spurt or change in diet requiring therapy adjustment. [PMID: 12662398] This term represents
the calculated result for free copper level as a fraction of the total copper measurement.;
