10-35 ug/g dry weight
Result Interpretation
35-250 UG/G Dry Weight.........High. Excessive copper at
this level can be associated with cholestatic liver disease,
such as primary biliary cirrhosis,primary sclerosing cholangitis,
autoimmune hepatitis, and familial cholestatic syndrome.
The heterozygous carriers for Wilson disease occasionally
have modest elevated values, but rarely higher than
125 UG/G of dry weight. In general, the liver copper content
is higher than 250 UG/G dried tissue in Wilson disease patients.
250-1000 UG/G Dry Weight.......High. This finding is suggestive
of possible Wilson disease.
>1000 UG/G Dry Weght........Very High. Strongly suggestive
of Wilson disease.
