Interpretation:

Reticulocyte Hemoglobin Equivalent (RET-He):The measurement of reticulocyte hemoglobin content is a direct assessment of the incorporation of iron into erythrocyte hemoglobin and thus a direct estimate of the functional availability of iron into the red blood cell. Low values indicate inadequate iron supply relative to demand. Referenced from: Brugnara, C., Schiller, B., Moran, J. (2006). Reticulocyte hemoglobin equivalent (Ret He) and assessment of iron-deficient states, Clinical Laboratory Hematology, 18:303-308.
