 Oftentimes, nutritional deficiencies that lead to blood cell changes are multiple. And so an individual with iron deficiency may also have deficiencies in folic acid or B12 that lead to nuclear maturation delay. So there's going to be a mixed picture which would only be unraveled once you start reversing the iron deficiency. So it's not unusual and indeed you ought to take note as you treat individual deficiencies to expect to amass other deficiencies hidden underneath the primary deficiency. So you will find that the majority of cells would be moving from a macrocytic stage to a normalcytic or a microcytic stage to a normalcytic. But as you did that you would now recognize a small population of cells that have a large volume and that should give you the hint. So your distribution curve will unravel a different colony.
