My doctor says I have big red blood cells, but my iron is fine... What does this mean?

Macrocytosis. Large red cells, or macrocytosis, can be due to vitamin deficiencies (b12, folate, (folic acid) thiamine), alcohol use, an underactive thyroid, liver disease, excessive production of new red blood cells (reticulocytosis), and bone marrow disorders such as myelodysplastic syndrome. Some people are born with big red cells. Please see a hematologist so that the correct diagnosis can be made.

Probably anemia. "range" on a lab test is where 95% or so of healthy people fall. Your physician is probably telling you that your are mildly anemic, and you will get a workup for possible blood loss or hemolysis if this is new.
