Accuracy of capillary HemoCue in comparison to venous Cell-Dyn hemoglobin values in healthy blood donors. Nine of 150 donors (6%) had “false-pass” HemoCue values, and five of 150 (3%) had “false-fail” HemoCue values when compared with Cell-Dyn reference values, using 12.5 g/dL as the criteria for deferral. Dashed line is the line of identity between HemoCue and Cell-Dyn values.
