In haematological patients, both transfusion load (RBC) and ferritin can be used to estimate iron concentrations (HICest). The number of RBC units was more accurate, with better correlations in estimating liver iron concentration with linear fit. (a) The correlation between hepatic iron concentration and RBC (range 0–144) is demonstrated with the equation HICest(transfusion)=4.6RBC+2.1. (b) The correlation between hepatic iron concentration and ferritin is demonstrated with the equation HICest(ferritin)=0.12ferritin−77.
