320:: Since the spleen is important for protecting against encapsulated organisms, sepsis caused by encapsulated organisms is a possible complication of splenectomy. The option of partial splenectomy may be considered in the interest of preserving immune function. Research on outcomes is currently limited, but favorable.

Spherocytosis can be diagnosed in
Peripheral blood film by seeing spherical red blood cells rather than biconcave. Because spherical red blood cells are more prone to lysis in water (because they lack some proteins in their cytoskeleton) there will be increased osmotic fragility on acidified glycerol

Treatment may vary depending on the cause of the condition. In the case of hereditary spherocytosis, although research is ongoing, at this point there is no cure for the genetic defect that causes hereditary spherocytosis. Current management focuses on interventions that limit the severity of the
