Iron deficiency anemia develops when body stores of iron drop too low to support normal red blood cell (RBC) production. Inadequate dietary iron, impaired iron absorption, bleeding, or loss of body iron in the urine may be the cause. Iron equilibrium in the body normally is regulated carefully to ensure that sufficient iron is absorbed in order to compensate for body losses of iron.
CBC results in iron deficiency anemia include the following:
-
Low mean corpuscular volume (MCV)
-
Low mean corpuscular hemoglobin concentration (MCHC)
-
Elevated platelet count (>450,000/µL) in many cases
-
Normal or elevated white blood cell count
Peripheral smear results in iron deficiency anemia are as follows:
-
RBCs are microcytic and hypochromic in chronic cases
-
Platelets usually are increased
-
In contrast to thalassemia, target cells are usually not present, and anisocytosis and poikilocytosis are not marked
-
In contrast to hemoglobin C disorders, intraerythrocytic crystals are not seen.
