[Studies of the deformability of preserved red blood cells using a simple filtration method]

The applied method to measure the filtrability of red blood cells is accurate enough for the study of the effects of the conditions of storage on their deformability. In this work the standard deviation of the method, the mean biological deviation of the deformability of human red blood cells and their deformability in the course of storage in the ACD-AG-medium have been investigated. Considerable loss of deformability occurs towards the end of storage time of the cells, which is not reversible be restitution of ATP alone. The applicability of this method as a simple test of the vitatity of preserved erythrocytes if to be tested.
