Abstract:
Objective To compare the leukocyte-reduced red blood cells and plasmas respectively prepared by automated blood components separator and manual method so as to provide theoretical basis for automatic and standardized flow of blood components preparation.MethodsThe prepared red blood cells and plasma were measured on the hemoglobin concentration,mean corpuscular volume (MCV),red blood cell count (RBC),haematocrit (HCT),mean corpuscular hemoglobin (MCH),mean corpuscular hemoglobin concentration (MCHC),average red blood cell volume distribution width,plasma weight and protein content after the first separation,preparation time and etc.These results obtained from different methods were compared and analyzed.Results The plasma weight after the first separation which was one-off prepared were (267.57 ±16.31) g (by automatic method) and (246.06±22.48) g (by manual method) (P＜0.05) respectively.The preparation time were (66.66±9.01) s (by automatic method) and (162.33±22.00) s (by manual method) (P＜0.05) respectively.Other results had no significant difference (P＞0.05).Conclusion All blood components products in this research meet the criterion of GB 18469-2012.However,the quality and separation efficiency of products made by automatic blood component separator are obviously higher than those by manual method.
