Stability of Hematologic Parameter in Storaged Blood

Abstract

Abstract: Hematological parametric values have been studied by automatic cell counter 'Coulter Gen S' in blood samples obtained from a group of 35 healthy volunteers , kept at room temperature and 4 C for 6, 24, 48 and 72 hours.When the blood samples are kept for 6 hours at room temperature and 4 C, the various hematological values when compare with at O hour are not significantly different (p > 0.05). When kept blood for 24 hours at room temperature and 4C, white blood cell count and differential white blood cell count are significantly changed (p < 0.05). Red blood cell parametric values at room temperature are less stable than at 4 C, changes occur at 24 hours.At 4 C, red blood cell parametric values,even kept 72 hours when compare with at O hour, are not significantly different (p > 0.05) except for the mean corpuscular volume. When kept blood for 24 hours at room temperature and 4' C, platelet counts are significantly changed, but the mean platelet volume at room temperature are stable at 4 C when intermittent agitated.
