Hepatic Iron Content (HIC) 200-​2,000 µg/g of tissue 200-​1,600 µg/g of tissue
Hepatic Iron Index (HII) Less than 1.0 Less than 1.0
Interpretive Data
A Hepatic Iron Index (HII) is not calculated for patients less than 14 years. An HII less than 1.0 is consistent with normal iron accumulation. An HII 1.0 through 1.9 is consistent with mild iron accumulation such as in heterozygous hemochromatosis or alcoholic liver disease. An HII greater than 1.9 is consistent with iron overload such as in homozygous hemochromatosis, porphyria cutanea tarda, and cirrhotic liver disease. The HII will decrease with chelation, chronic blood loss, or phlebotomy.
