Red blood cell-deformability measurement: review of techniques.

abstract：INTRODUCTION:The hormones erythropoietin (EPO) and thrombopoietin (TPO) are main regulators of erythro- and thrombopoiesis. Cell loss caused by operative procedures may alter serum levels of the hormones, resulting in well known phenomenons like reactice thrombocytosis. MATERIAL AND METHODS:Blood samples from 10 patie...
