Objective To analyze the status of blood discard from voluntary blood donation in Zhengzhou in the period ranging from 2013 to 2017, so as to propose countermeasures to minimize the blood wasted. Methods The rate of blood donations discarded due to detection and non-detection causes of the targeted years were statistically analyzed by Tangshan Oi′ao software system. Results Within the studied period, the total rate of blood discard was 2.496%(24 402/977 761). The most common cause of blood discard owing to blood screening was ALT, accounting for 1.406%(13 751/977 761), followed by HBsAg 0.362%(3 541/977 761), anti-HCV 0.321%(3 136/977 761), anti-TP 0.269%(2 633/977 761), and anti-HIV 0.137%(1 341/977 761). Regarding annual discard rate, a significant difference between each year was observed except for 2013 and 2014. The mean annual discard rate was(2.521±0.428) %, ranging from 2.001%(4 285/214 115) in 2017 to 2.993%(5 726/191 315) in 2014. The total rate of blood discarded owing to nucleic acid detection was 0.488‰(371/760 687), among which HBV DNA accounted for 0.480‰(365/760 687), HIV RNA 0.005‰(4/760 687), and HCV RNA 0.003‰(2/760 687). Comparing NAT discard rate, HBV DNA discard rate was significantly higher than that of HCV RNA and HIV RNA, and there was no significant difference between HCV RNA and HIV RNA discard rate(P0.05). The total non-detection discard rate was 3.206%(134 335/4 189 536), among which lipemia ranking in the first with a rate of 2.797%(117 182/4 189 536), followed by bag leakage 0.235%(9 848/4 189 536), blood clot 0.086%(3 604/4 189 536), expired blood 0.062%(2 597/4 189 536), blood deficiency 0.023%(945/4 189 536), hemolysis 0.003%(116/4 189 536) and abnormal color 0.001%(43/4 189 536). In addition, discard rates in blood preparations were as follows : 42.63% in concentrated platelets(3 832/8988), 12.4033% in frozen plasma(117 648/948 521), 1.361% in inactivated frozen plasma(8 243/605 521), 0.431% in cryoprecipitation(1 209/280 368), and 0.393% in whole blood(17/4 331). Conclusion Blood Bank should not only strengthen the consultation before blood donation, but also standardize the process of blood collection, supply and clinical use aiming at reducing blood wasted.
