Population characteristics, blood quality and adverse reactions of blood donation in different blood collection sites / 中国基层医药

Unpaid blood donation is the important way of clinical blood supply. The blood collection environment of blood stations mainly includes mobile blood collection vehicles, blood donation rooms and other mobile forms or fixed places to recruit blood donors and collect blood. During the process of blood collection, in addition to the individual organism of the blood donor, different blood collection sites have certain impact on the quality of the whole blood collected from the donor and the adverse reactions in blood donors. To further investigate the distribution characteristics of the collected whole blood, improve blood quality and reduce adverse reactions, we reviewed relevant studies worldwide to analyze the population characteristics, advantages and disadvantages in different blood collection places, which will help establish different blood collection sites as blood stations and increase the amount of collected blood and improve blood quality.
