WebNov 15, 2013 · Currently, the eosin 5-maleimide (EMA) binding test and hypertonic cryohemolysis (HCH) test have been proposed as screening tests in recently published guidelines for the diagnosis of HS (Br J Haematol 2012;156:37-49). And the flow cytometric OF (FC OF) test is recently developed as an assay that can replace the classical OF test. WebHuman erythrocytes suspended at 37°C in hypertonic solution of either electrolytes or nonelectrolytes undergo hemolysis when the temperature is lowered toward 0°C (Green, F.A., Jung, C.Y. 1977J.
