However, the ability to accurately detect PNH RBCs is compromised by prior hemolysis and/or transfused RBCs," researchers in Toronto, Canada report.

"with aplastic anemia (AA) and myelodysplastic syndrome (MDS) can also produce PNH clones. We recently described a multiparameter fluorescent aerolysin (FLAER)-based flow assay using CD45, CD33, and CD 14 that accurately identified PNH monocyte and neutrophil clones in PNH, AA, and MDS. Here, we compared the efficiency of this WBC assay with a CD59-based assay on RBCs...
