WebEchinocytes are spiculated RBCs in which the spicules are relatively evenly spaced and of similar size. When observed in stained blood films, echinocytosis is usually an artifact that results from excess EDTA, improper smear preparation, or prolonged sample storage before blood film preparation. WebThe spherocyte is a thick red cell because—as compared with the normal erythrocyte—its surface area encloses a relatively larger volume. The disproportion may come about by increasing the volume, which occurs in hypotonic solutions and during periods of stagnation, either in the spleen or in the test tube. but used matress topper
