RBC morphology at the end of the storage period for a sample with high stomatocyte counts, low type III echinocytes, low MI, and high hemolysis (16.9, 13.2, 0.37, and 1.2%, respectively; a), and a sample with low stomatocyte counts, high echinocyte counts, high MI, and low hemolysis (1.0, 25.8, 1.11, and 0.09%, respectively; b). Scale bars, 5 µm. The full fields of view for a and b are shown in online supplementary Figures S1 and S2. Representative discocytes are circled on both images; representative stomatocytes on either side of the circled discocyte in a are indicated by asterisks.
