Polychromasia
Polychromasia
Polychromasia (pronunciation: /ˌpɒlɪkroʊˈmeɪziə/) is a medical term that refers to the presence of red blood cells in the blood that are stained in various shades of color.
Etymology
The term "Polychromasia" is derived from the Greek words "poly" meaning many, and "chroma" meaning color.
Definition
Polychromasia is a condition observed in a Peripheral blood smear where there is an increased number of immature red blood cells (RBCs), known as Reticulocytes, that appear in various shades of color when stained. This condition is often indicative of increased RBC production in the Bone marrow.
Clinical Significance
Polychromasia is usually a sign of Anemia or other conditions where the body is producing more red blood cells to compensate for a loss or destruction of mature RBCs. It can also be seen in conditions like Hemolytic anemia, Sickle cell anemia, and after a Blood transfusion.
Diagnosis
Polychromasia is usually diagnosed through a peripheral blood smear test, where a sample of the patient's blood is examined under a microscope. The presence of polychromasia can be confirmed by the appearance of reticulocytes that are larger and more bluish in color than mature RBCs.
Treatment
Treatment for polychromasia typically involves addressing the underlying cause of the increased RBC production. This may involve treating the anemia or other blood disorders that are causing the body to produce more red blood cells.
