Polychromasia is increased in hemolysis, blood loss, and marrow infiltration. All polychromatophilic cells are reticulocytes, however, not all reticulocytes are polychromatophilic.

If the serum ferritin level is not initially low, further evaluation should include total iron-binding capacity, transferrin saturation level, serum iron level, and possibly hemoglobin electrophoresis. They generally live for about 120 days before they die off and need to be replaced. Polyhydramnios occurs in about 1 to 2 percent of pregnancies.

Monitoring of iron status in patients with heart failure. This can cause reticulocytes to be released into the blood prematurely as the body compensates for the lack of RBCs. Some of the known causes of polyhydramnios include: Often, however, the cause of polyhydramnios isn't clear. This pattern of granulation was also seen in several types of toxic poisoning, especially lead poisoning.

Polychromatophilic cells are young red blood cells that have been recently released from the bone marrow. It's an indication of red blood cells being released prematurely from bone marrow during formation. People with other types of anemia, like sickle cell anemia or thalassemia, may require blood transfusions to treat their condition.

EPO is usually released in response to anemia (a lowered number of RBCs in the blood), so anemia should be considered a cause of polychromasia. 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. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder that causes red blood cells to break down sooner than they should. These cells are likely reticulocytes, which are immature non-nucleated red cells which have only just extruded their nuclei.
