Clinical Information Spherocytes are osmotically fragile cells that rupture more easily in a hypotonic solution than do normal RBCs. Because they have a low surface area:volume ratio, they lyse at a higher osmolarity than do normal discocyte (RBCs).
WebSpherocytes are found on the blood film, usually accounting for 15% to 20% of cells. • The presence of spherocytes in the blood can be confirmed by an osmotic fragility test (however the osmotic fragility test is not specific for hereditary spherocytosis and may be abnormal in immune and other hemolytic anemias). •
