Red Cell Function Tests
The total number of red cells per volume of blood, red cell volume, cellular hemoglobin, and density distribution are determined by Advia 120 analysis. Erythropoiesis is measured by reticulocyte count and factors such as erythropoietin (EPO). Blood flow can be visualized in humans by the use of cytoscan technology and red cell deformability is measured by exposing the red cell population to a fluid shear stress in the Ektacytometer. The Hemox Analyzer is used to measure Oxygen Affinity, a red cell characteristic determined by both hemoglobin, and cytosolic composition including 2,3 DPG. PS exposure as measured by flowcytometry is related to red cell survival, increased interaction with other blood cells, and imbalance of hemostasis.
