| Rather, iron status should be measured directly, using indicators like serum ferritin or red blood cell protoporphyrin. |
| The iron can be stored within intestinal enterocytes bound to ferritin. |
| They all had ferritin levels less than 50 micrograms per liter, at the lower end of normal. |
| How best can we then differentiate microcytic anaemia of chronic disease from genuine iron deficiency when ferritin values are normal? |
| High concentrations of the iron carrying protein ferritin are a marker of haemochromatosis. |
| The level of ferritin must always be correlated with the level of C-Reactive Protein or with the sedimentation rate. |
