Aquí presentamos técnicas para medir la deformabilidad del glóbulo rojo y la heterogeneidad celular por ektacytometry. Estas técnicas son aplicables a las investigaciones generales de la deformabilidad del glóbulo rojo y las investigaciones específicas de enfermedades de la sangre caracterizadas por la presencia de rígidos y deformables eritrocitos en la circulación, tales como anemia de células falciformes.
