No: Hemoglobin level determines if u r anemic. However, simplified, the size of red blood cells (rbc) can be small and mean iron deficiency, or large and mean Folic Acid or B12 deficiency. Causes of iron deficiency is loss of blood (iron molecule is in the rbc), without there being a store of iron in the body for the bone marrow to make more of them. Must be treated. Call doc.
