Because of this, reticulocytosis is a possible lab finding in sickle cell disease. [5] Hereditary spherocytosis: a genetic disorder where defects in red blood cell membrane proteins cause them to lose their normal shape, becoming spherical (spherocytes) which are prone to getting stuck and rupturing in the spleen. This hemolysis creates a ...
For people living with the disease, a sickle cell crisis can happen at any time. When it does, their rigid, sickle-shaped red blood cells become stuck in their blood vessels, blocking flow and ...
