National Health Service. RBCs are released prematurely in response to a certain type of hormone stimulation usually resulting from anemia or possibly due to structural damage to the bone marrow from a variety of causes. Polychromasia is the most important indicator of responsiveness to anemia, and may be further quantitated by counting reticulocytes.

There can be complications from the underlying condition thats causing anisopoikilocytosis. Transferrin saturation is a percentage calculated as serum iron concentration/TIBC 100. Most RBCs are made and mature in the bone marrow. [citation needed], Polychromasia can be detected through the use of stains that will change the color of the red blood cells that are affected.

[6] The absolute number of reticulocytes is referred to as the reticulocyte index and is calculated by adjusting the reticulocyte percentage by the ratio of observed hematocrit to expected hematocrit to get the 'corrected' reticulocyte count.
