Abstract
BACKGROUND & AIMS: To evaluate the correlation between the iron absorption and the induced increase in serum iron concentration (S-Fe) after 1 h. METHODS: Eleven subjects were after an over night fast served a wheat roll fortified with 100-mg iron as ferrous sulfate labelled with radio iron. The S-Fe response and the iron absorption measured by whole body counting, were studied. RESULTS: There was a significant correlation between the iron absorption and the S-Fe increase (R2 = 0.75, P < 0.001). CONCLUSION: This short and valid observation period proposes the S-Fe procedure as an uncomplicated and clinically applicable tool when evaluating the iron absorption capacity of patients.
