Abstract: PURPOSE: A disk-shaped microfluidic system and a method for measuring deformability of blood cells are provided to extract plasma from blood and to check blood condition. CONSTITUTION: A method for measuring deformability of blood cells comprises: a step of feeding blood to a disk-shaped centrifugal container; a step of centrifuging the blood into blood cells and plasma; a step of detecting moving distance of the blood cells; a step of calculating a first graph indicating the moving distance and a second graph indicating theoretical moving distance; and a step of measuring deformability of the blood cells.
