Q

What is the difference between the increased and decreased reticulocyte count?

A

-Increased Retic Count (> 2%)
Bone marrow is adequately responding to anemia
Blood loss, hemolysis, response to therapy
-Decreased Retic Count (< 2%)
Inability of bone marrow to compensate for anemia
Normocytic, Microcytic, Macrocytic anemias
