The minimum hemoglobin cutoff for blood donation in India is 12.5 gm% for both male and female donors and the minimum donation interval is 3 months. Donation of one unit of blood results in decrease in hemoglobin by 1 gm% and loss of 200-250 mg of iron. Donor deferral due to anemia is one of the major reasons of temporary rejection of blood donors. In the absence of further workup or advise, it results in loss of valuable donor base.
To provide baseline information regarding the prevalence and spectrum of anemia in prospective blood donors to help plan a future strategy for donor management.
Hemoglobin testing of donors was performed using Hemocue and Copper sulfate specific gravity method. Ethylene diamine tetraacetic acid sample of all the donors who failed either or both the screening tests was tested on automated analyzer for evaluation of hemoglobin and red blood cell indices.
Of all the donors, 15.5% were deferred due to anemia. Prevalence of anemia in prospective blood donors was 1.8%. It was significantly higher in female donors compared with male donors (34.2% vs 1.2%). The most common type of anemia was normocytic normochromic.
在印度，男性和女性献血者的最低血红蛋白临界值均为12.5克/百分比，最短献血间隔为3个月。捐献一个单位的血液会导致血红蛋白下降1克/百分比，并损失200 - 250毫克铁。因贫血导致的献血者延期是暂时拒绝献血者的主要原因之一。在没有进一步检查或建议的情况下，这会导致宝贵的献血者群体流失。
提供有关未来献血者贫血患病率和类型的基线信息，以帮助制定未来献血者管理策略。
使用血红蛋白仪和硫酸铜比重法对献血者进行血红蛋白检测。对所有一项或两项筛查试验不合格的献血者的乙二胺四乙酸样本在自动分析仪上进行检测，以评估血红蛋白和红细胞指数。
在所有献血者中，15.5%因贫血而延期。未来献血者中贫血的患病率为1.8%。女性献血者的贫血患病率显著高于男性献血者（34.2%对1.2%）。最常见的贫血类型是正细胞正色素性贫血。
