| Additional information | To convert µg to µmol (SI units) multiply x 0.0179 The hepatic iron index (provided for patients =12 years old) is derived from the formula µg of iron per g of dry liver weight/56 x age. Results between 1.0 and 1.9 suggest mild, nonspecific iron accumulation as may be seen in alcoholic liver disease or heterozygous hemochromatosis.
