Whole blood glucose is the glucose concentrationof directly measured whole blood.  Because the blood cells occupy a certain volume of the whole blood, the glucose concentrationof whole blood is lower than that measured in other ways. Plasma is the liquid from blood cells that are separated from the whole blood using anticoagulant; it includes all components of blood except cells. Serum is the liquid part when the coagulated blood is centrifuged. Because of centrifuging, serum contains neither blood cells nor blood coagulation factors; therefore, the glucose concentration of plasma is recognized in conformity with that of serum. The tissue fluid doesn’t contain blood cells, the soluble components of which are basically the same as those of stable plasma. Thus, the subcutaneous tissue fluid glucose tested by sensor which is in dynamic balance is consistent with plasma and serum glucose, but always higher than the concentrationof whole blood.
