WebConclusion Flow‐cytometric osmotic fragility test is the best possible single test followed by EMA for diagnosis of HS. A combination of FOFT and EMA can correctly diagnose 100% patients. These ... Web[3]. Various tests such as red cell osmotic fragility test (OFT), acidified glycerol lysis time (AGLT) test, osmotic gradient ektacytometry, hypertonic cryohemolysis test, eosin-5-maleimide (EMA) binding test and flow cytometric osmotic fragility test (FC-OFT) are available for making diagnosis [4–7]. Still in most of the
WebBackground: The cytometric flow osmotic fragility test (FC-OFT) was recently introduced. However, the test is still under development and some variables have not yet been fully tested. Methods: The osmotic fragility of hereditary spherocytosis (HS) cases and healthy controls were evaluated by FC-OFT using a series of tubes containing decreasing ... WebIn addition to the “tried and true” method of mechanical osmotic fragility, in recent years a flow cytometric assay has been developed for the assessment of hereditary spherocytosis and other RBC membrane disorders [19]. This assay, called the eosin-5′-maleimide (EMA) test, works by the principle of EMA binding to the band 3 protein, an ...
