2020-11-18 · 1 INTRODUCTION. Liver iron concentration (LIC) measurement is necessary for evaluation of a variety of iron-loading disorders including hereditary HFE hemochromatosis, thalassemia, sickle cell anemia, aplastic anemia, and myelodysplasia. 1, 2 Iron overload is a systemic disorder characterized by a high level of iron in the plasma and functional cells and
Hepatic iron stores and plasma ferritin concentration in ...
The 95% prediction intervals for hepatic iron concentration, given the plasma ferritin, were so broad as to make a single determination of plasma ferritin an unreliable predictor of body iron stores. Variability resulting from factors other than iron status limits the clinical usefulness of the plasma ferritin concentration as a predictor of ...
