There are several different types of anemia, with additional testing needed to differentiate among the various types. If the number of RBCs is decreased below normal, the condition is known as anemia. The result is the production of an increased number of red blood cells, a condition known as polycythemia. Such hypoxia occurs in individuals living at high altitudes or in people who smoke. The amount of erythropoietin secreted increases whenever tissue hypoxia occurs. RBC production is stimulated by erythropoietin, a hormone secreted by the kidney. The cell is also able to change its shape when necessary to allow for passage through the smaller capillaries. To enable use of the maximal amount of Hb, the RBC is shaped like a biconcave disk-this affords more surface area for the Hb to combine with oxygen. Conversion: to convert from the conventional unit to the SI unit, multiply by the conversion factor to convert from the SI unit to the conventional unit, divide by the conversion factor. This process is achieved by means of the Hb in the RBCs, which combines easily with oxygen and carbon dioxide and gives arterial blood a bright red appearance. The following table provides factors for converting conventional units to SI units for selected clinical data. The main function of the red blood cell (RBC or erythrocyte) is to carry oxygen from the lungs to the body tissues and to transfer carbon dioxide from the tissues to the lungs. It is used in The Review of Diabetic Studies. weight indications in grams, milligrams and kilograms.

The red blood cell (RBC) count is a measure of the number of red blood cells (erythrocytes) per cubic millimeter (mm3) or liter (L) of blood.
