Question: what is the difference between low iron and low hemoglobin?
Answer: When a person's iron stores are low, as in your case, that condition is known as iron deficiency. If the body uses up all the iron stored in ferritin, then it can't make hemoglobin. A low level of hemoglobin is anemia. When your blood test showed low iron stores, that meant the amount of ferritin in your blood was low.
