Abstract
A method and device is provided for simply and rapidly measuring erythrocyte deformability by placing samples of blood on a set of porous membranes or a membrane strip with graded series of sharply defined pore sizes to determine the selective absorption thereon. Based on observation of the selective absorption on the membranes or membrane strip the deformability index of the erythrocytes may be determined.
