Polychromatophilic cells are young red blood cells that have been recently released from the bone marrow. I apologize for my previous question. Erythropoetin, a hormone made by the kidneys, controls the production of red blood cells as well as the rate at which they are released from the bone marrow. The most common causes of microcytosis are iron deficiency anemia and thalassemia trait. There are no symptoms for polychromasia itself.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare blood disorder that causes hemolytic anemia, blood clots, and bone marrow dysfunction. [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.

The most common cause of bone marrow damage is penetration by cancer cells, either from the bone marrow itself or as a consequence of metastasis from another part of the body. Anemia of chronic disease is suggested by low iron levels and decreased total iron-binding capacity. They are larger than mature red cells, and are bluish in color. Another cause is bone marrow fibrosis, in which uncontrollable growth of immature blood cells of various types leads to the formation of scar tissue that damages the bone. Hemolytic anemia.
