Anemia is usually classified based on the size of RBCs, as measured by the mean corpuscular volume (MCV). Anemia can be microcytic (MCV typically less than 80 Î¼m3 [80 fL]), normocytic (80 to 100 Î¼m3 [80 to 100 fL]), or macrocytic (greater than 100 Î¼m3 [100 fL]).
The results of a CBC indicate the amount of hemoglobin in the red blood cells. The hemoglobin count is the most useful indicator of anemia because it determines the oxygen-carrying capacity of the blood. The normal hemoglobin count is 12 g/dl â 16 g/dl for women and 14 g/dl â 18 g/dl for men.nemia occurs because patients canât produce enough red blood cells or because red blood cells are lost through bleeding or destroyed faster than they can be produced. The production of red blood cells in the bone marrow is called erythropoiesis. Erythropoiesis is controlled by red blood cell growth factors.
