On the other hand, focusing early on the question of production (e.g., via the reticulocyte count) may allow the clinician more rapidly to expose cases where multiple causes of anemia coexist. The morphologic approach uses a quickly available and cheap lab test as its starting point (the MCV). Anaemia can be classified in a variety of ways, based on the morphology of RBCs, underlying etiologic mechanisms, and discernible clinical spectra, to mention a few.ĭifferent clinicians approach anemia in different ways two major approaches of classifying anaemias include the "kinetic" approach which involves evaluating production, destruction and loss, and the "morphologic" approach which groups anaemia by red blood cell size. There are several kinds of anemia, produced by a variety of underlying causes. In menstruating women, dietary iron deficiency is a common cause of deficient red blood cell production.Īnemia is the most common disorder of the blood. The three main classes of anaemia include excessive blood loss (acutely such as a hemorrhage or chronically through low-volume loss), excessive blood cell destruction ( hemolysis) or deficient red blood cell production (ineffective hematopoiesis). Hemoglobin (the oxygen-carrying protein in the red blood cells) has to be present to ensure adequate oxygenation of all body tissues and organs. This results in a reduced ability of blood to transfer oxygen to the tissues, causing hypoxia since all human cells depend on oxygen for survival, varying degrees of anaemia can have a wide range of clinical consequences.
