PTPRC and myelodysplastic syndrome: After an interim analysis that included the first 98 samples suspected for MDS and all blood samples from HD we decided to omit 10 of the initial 23 parameters due to low sensitivity (mean fluorescence intensity (MFI) of FSC, SSC, CD10, CD11a, CD45, CD66, CD116) or low specificity (percentage of granulocytes, lymphocytes-to-granulopoiesis-ratio, MFI CD177).
