Ferritin in whole blood donors: an investigation in Beijing / 中国输血杂志

ABSTRACT

【Objective】 To detect the ferritin of whole blood donors in Beijing, and to analyze the influencing factors related to low level of ferritin, so as to provide scientific basis for iron supplementation of blood donors. 【Methods】 Ferritin was detected among 27 071 blood donors in Beijing area from March to June 2018. Related information of blood donors with low ferritin level was analyzed using Logistic regression analysis to determine the type of blood donors most likely to present low ferritin level. 【Results】 The rate of low ferritin value in whole blood donors in Beijing was 8.54%. The abnormal low ferritin was affected by gender, repeat donation behavior and the number of blood donations within one year, and not by age.The gender and the number of blood donations within one year presented great impact, with OR value at 8.258(CI7.463~9.137)and 2.148(CI1.856~2.485), respectively. 【Conclusion】 The iron storage status of whole blood donors in Beijing area under the current blood policy is better than that in other developed countries, revealed by a large-scale population survey, yet more attention should be paid to the ferritin status of repeat blood donors.
