Abstract

We measured red blood cell zinc protoporphyrin/heme (ZnPP/H) ratios in premature infants at hospital discharge. ZnPP/heme ratios correlated directly with red blood cell distribution width and reticulocyte number. As in other populations, ZnPP/H ratios may provide a simple measure of iron-deficient erythropoiesis in premature infants.
