echinocyte

Burr cell, crenated cell Hematology An RBC with 30+ crenations, bumps or spurs, which reflect damage to the normal cell membrane by various lytics–eg, saponin, bile salts, ionic detergents, lecithin; slow drying; aged blood; rarely, echinocytes reflect disease–eg, uremia or pyruvate kinase deficiency.
