Establishment and application of measurement range of main blood quality indicators in provincial blood stations
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 8
Abstract
Objective To obtain the monitoring measurement range of quality indicators of red blood cells, plasma and derivatives and leukocyte-reduced apheresis platelets provided by blood stations in Hebei province, explore the distribution of monitoring values and the change of monitoring level, so as to further strengthen the homogenization construction of quality control laboratories in blood stations in Hebei. Methods In 2023, the sampling data of 12 blood stations in Hebei from 2015 to 2022 were collected, scatter plots were made and the range markers were set, and the "mean±SD" line was taken as the upper limit and lower limit of the measurement range. In 2024, the monitoring values in 2023 were added, and the changes of two measurement ranges were compared to analyze the stability and overall level. Results Comparison of the measurement range from 2015 to 2022 and the measurement range from 2015 to 2023 showed that the standard deviation of the content of deleukocyte suspension of red blood cells-hemoglobin, washed erythrocyte-hemoglobin, washed erythrocyte-supernatant protein, cryoprecipitate coagulation factor-FⅧ, fresh frozen plasma-FⅧ, leukocyte-reduced apheresis platelets-leukocyte residue and leukocyte-reduced apheresis platelet-red blood cell concentration decreased from 8.132 to 7.993, 6.252 to 6.104, 0.273 to 0.267, 57.506 to 56.276, 0.920 to 0.892, 0.653 to 0.644 and 2.653 to 2.603, respectively.The narrowing of the standard deviation range of the above items led to more concentrated monitoring values and reduced dispersion. Comparison of the measurement range from 2015 to 2022 and the measurement range from 2015 to 2023 showed that the mean value of leukocyte residue of the deleukocyte suspension of red blood cells, hemoglobin content of the wash erythrocyte, protein content of supernatant of the wash erythrocyte, hemolysis rate of the wash erythrocyte, FⅧ content of the cryoprecipitate coagulation factor, plasma protein content of the fresh frozen plasma, FⅧ content of the fresh frozen plasma, platelet content of the leukocyte-reduced apheresis platelets changed from 0.362 to 0.476, 44.915 to 44.861, 0.280 to 0.283, 0.137 to 0.142, 133.989 to 133.271, 60.262 to 60.208, 1.301 to 1.277 and 3.036 to 3.033, respectively, and was closer to the national standard line, which reflects an increase in the number of unqualified monitoring values or values close to the national standard line in 2023. The long-term qualified rate of coagulation items was low, and no improvement has been observed. The stability of biochemical items has been enhanced but overall deviation has occurred, with the average value close to the national standard line. The possibility of subsequent testing failure has increased. The counting items showed no obvious common characteristics. Conclusion The use of "mean±SD" in the analysis can visually display the distribution of monitoring values of different items in Hebei, forming an indicator measurement range covering the past nine years. It shows the characteristics of each item, and provides reference for subsequent quality control laboratory data analysis of each blood stations to takes active measures to improve the monitoring level.
