Her præsenterer vi teknikker til at måle roede blodlegemer deformability og cellulære heterogenitet af ektacytometry. Disse teknikker anvendes til generelle undersøgelser af roede blodlegemer deformability og specifikke undersøgelser af blodsygdomme karakteriseret ved tilstedeværelsen af både stive og deformerbare røde blodlegemer i cirkulation, såsom seglcelleanæmi.
