What is the oxygen carrying capacity of reticulocytes? What is the oxygen carrying capacity of immature red blood cells, or reticulocytes? Is there any difference between oxygen carrying capacity of mature and immature red blood cells?

This was studied by Steve Fishbone et al and concluded that the Hb content of a Reticulocyte is slightly higher than that of a mature RBC. The CHr, which is the Hb content of a reticulocyte in CRF patients receiving Erythropoetin is around 27.5 +/- 2.5 pg
