Descripción de la celda:
Los picocitos aparecen como glóbulos rojos pequeños, oscuros y picnóticos que carecen de palidez central y tienen una forma irregular, no esférica.
Formación de células:
Los picocitos son raros, pero pueden formarse como resultado de la deshidratación de los glóbulos rojos o del daño oxidativo.
