| Abstract: | Human red blood cells frozen by the high glycerol method and washed in the Haemonetics, IBM, and Elutramatic cell washers showed uniformly low hemolysis and modest differences in the loss of intact cells during washing. Residual leukocytes ranged from an apparent absence of cells to as many as 103/mm3. Configuration changes in the Haemonetics bowl designed to improve mixing also improved leukocyte removal. |
