Sampling data of fresh frozen plasma, cryoprecipitates and leukocyte-free platelet quality monitoring in Hebei Province from 2015 to 2021: a retrospective analysis
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 6
Abstract
Objective To form the sampling data interval by retrospectively analyzing the sampling data of quality monitoring of fresh frozen plasma, cryoprecipitates and leukocyte-free platelets in all blood stations in Hebei Province during the past 7 years. Methods The data of blood component sampling from 12 blood station quality control laboratories in Hebei from 2015 to 2021 were collected. The FⅧ content and plasma protein content of fresh frozen plasma, the FⅧ content and fibrinogen content of cryoprecipitates, and the leukocyte residuals, red blood cell mixed and platelet content of leukocyte-free platelets were taken as the objects for discrete point and fitted curve analysis. Results The FⅧ level of fresh frozen plasma: (1.36±1.1) IU/mL, 5 blood stations showed a representative overall high or low or fluctuated characteristics; Fresh frozen plasm-plasma protein items: overall mean ±SD: (61.13±16.7) g/L, four blood stations showed scattered distribution or continuous high value scattered points; Cryoprecipitates FⅧ: the overall mean ±SD: (134.25±58.7) IU/mL, four blood stations showed the differentiation characteristics of continuous high, low or stable in the middle; Cryoprecipitates-fibrinogen items: the overall mean ±SD: (215.27±83.5) mg, five blood stations showed the overall high or low and fluctuated. Leukocyte-free apheresis platelet-to-leukocyte residual items: overall mean ±SD: 0.37±0.96 (×106/bag), two blood stations showed a relatively high representative overall characteristics, and the rest were concentrated between 0 and 1; The total mean ±SD of platelet-to-red blood cell mixture without leukocyte was 2.45±2.82 (×109/bag), with obvious segmented concentrated distribution, and scattered distribution in 3 blood centers. Platelet content: the overall mean ±SD was 3.14±1.55 (×1011/bag), many deviations were noticed in 3 blood stations, and 1 blood station showed representative overall high characteristics. Conclusion This analysis shows that the distribution status of each blood station in different items is similar. The distribution status of discrete point groups and the change trend of the concentrated part of the fitting curve show that there are some differences in the monitoring level between the quality control laboratories of each blood station, and the update of detection instruments and reagents and the selection of detection methods greatly affect the test results. The summary data presented the index interval framework formed in the past 7 years, which helped to understand the difference between the results of each laboratory, correct the accuracy of the test results, better play the guiding role of quality monitoring in the blood preparation process, and continue to enhance the standardization of the whole process of blood collection and supply in the province.
