Echinocytes-echinocytes are small, crenated (shrunken) erythrocytes characterized by the presence of 10-30 spikes or spicules on their outer membrane. normally they are most numerous within the first 24 hours of envenomation, before the development of clinical signs, and will affect almost 100% of the red blood cells. after 2-3 days, the echinocytes steadily decrease in number and eventually become absent on a blood smear. it is important to note, however, that in some animals echinocytes do not appear at all following envenomation and that appropriate medical therapy will still need to be implemented.
