IPSS-R Prognostic Values



Hemoglobin (Hgb) is a large iron-containing protein found in red blood. This protein is what makes ‘red cells’ red. Hemoglobin’s job is to pick up oxygen in the lungs, carry it in the red blood cells, and then release oxygen into the tissues that need it like the heart, muscles, and brain. Hemoglobin also removes carbon dioxide from the tissues and carries this waste product back to the lungs where it is exhaled.

Normal Hemoglobin Ranges

Men: 13.5 to 17.5 grams per deciliter (g/dL)
Women: 12.0 to 15.5 grams per deciliter (g/dL)
