Polychromatophilia refers to how blood cells looks undera microscope when the cells are stained with special dyes. It means there is more staining with certain dyes than normal. The extra staining is due to too manyimmature red blood cells (RBCs) called reticulocytes. These cells have a blue colored center.
Too many reticulocytes is most often seen when the bone marrow needs to make morered blood cellsbecause of a certain condition, such as hemolytic anemia.
This condition is also calledpolychromasia.
