Abstract : Small aliquots of red cells with low, normal and high P50 values were frozen with 40% W/V glycerol and stored at -80 C for at least 1 year. After thawing and washing, these red blood cells were used as controls for P50 measurements. In studies conducted over a 3-year period, this quality control system has been shown to be a convenient, stable and reproducible way to assess the instruments used for P50 measurements as well as the technicians conducting the tests.
