A retrospective cross-sectional study, based on documentary analysis of virtual medical records from the donor sector of the blood center of Amazonas, targeted all donors who opened a registry with the intention of donating blood in the 2017-2019 triennium. The data were filtered, tabulated and analyzed, exploring sociodemographic variables and reasons for postponement, where we highlighted the groups with the highest chances of unfitness and frequency of donations. The highest rates of postponement correspond to clinical screening for factors such as diet, sexual habits and risk exposures. The predominant donation is replacement, with female donors who have the highest rates of unfitness and in the first donation. The donor profile associated with demographic data makes it possible to analyze the characteristics and cyclical changes in blood donation, highlighting the factors that cause disability, which are simple and likely to be worked on to improve the scenario of blood donation. The study also provides evidence of the need to prioritize education and dissemination to strengthen the culture of blood donationAcesso AbertoDoação de sangueTriagem clínicaInaptidão de doadoresInability of donorsBlood donationDissertação
