A normal hemoglobin level is about 12 to 18 g/dL.
A red blood cell transfusion may be suggested if it drops below 8 g/dL. Whether you need a transfusion for anemia depends on many factors, such as how long it took for the anemia to develop and how well your body is able to cope with it.

This occurs in three stages:
  • First stage: Iron stores are depleted. ...
  • Second stage: When iron stores are low, the normal process of making red blood cells is altered. ...
  • Third stage: Iron-deficiency anemia develops because there isn't enough iron to make hemoglobin for red blood cells.
