The ongoing COVID\u201019 pandemic has adversely affected blood transfusion services all over the world. But its impact on donor deferral rate and the pattern is unclear in light of the new donor deferral policy due to the COVID\u201019 pandemic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>This retrospective study was divided into pre\u2010COVID and COVID (15 March 2019\u201314 March 2021). All the deferred donors were divided into six different categories: (1) medical causes, (2) surgical causes, (3) drugs and vaccination, (4) risk of transfusion\u2010transmitted diseases, (5) miscellaneous causes and (6) flu\u2010like symptoms. In addition, COVID\u2010related deferrals were also incorporated. All these above categories along with the donor demography were analysed by SPSS software version 25.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The donor deferral rate was 17.03% and 12.74% during the pre\u2010COVID and COVID periods, respectively. During the pre\u2010COVID period, Category 3 deferrals and during COVID period, Category 6 deferrals were significantly higher. A reversal in pattern with increased blood pressure (40.2% vs. 24.04%) over\u2010riding low haemoglobin (34.77% vs. 55.5%) was noted in the Category 1 deferral during the COVID period. Category 1 deferral was more in middle\u2010aged adults as compared to young and old adults (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.05). Among middle\u2010aged adults, deferral due to flu\u2010like symptoms was also significantly more during the COVID period (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>COVID\u201019 significantly affected the donor pool and changed the pattern of donor deferral.
