We reviewed scientific methods for measuring erythrocyte deformability such as micro pipette aspiration tech-nique, ektacytometry and nickel mesh filtration technique, from a quantitative and sensitive point of view. Then werepresented deformability of sickle cells and hereditary spherocytes including effects of medical treatments.Moreover, we showed a strong correlation between blood flow in vivoand erythrocyte deformability. Thus, we clari-fied physiological and medical significances of erythrocyte deformability.
