Background: Detailed analysis of various causes for deferral of blood donors may help medical personnel to curb the barriers that impede the blood donation. This study aims to evaluate the deferral reasons of a blood donor in our centre and to uncover the hindering factors behind the target of achieving 100% acceptance of blood donorsMethods: This is a retrospective record based study over a time period of 4 years from January 2012 to December 2015.Data were collected from the Donor deferral registry with respect to age and Gender. The causes of deferral were categorized as temporary and permanent.Result: A total of 9557 registered donors were screened and 1421 (14.87%) were deferred. Overall, men (1258; 88.5%) were deferred more than the women (163; 11.5%). But women had higher deferral rate (163/236; 69.1%) compared to Men (1258/9321; 13.5%). Temporary deferral (78.7%) was common than the permanent deferral (21.3%). Anemia with low hemoglobin was the commonest cause of temporary deferral (31.5%) in both males and females. Hypertension was the commonest cause of permanent deferral (75.8%) constituting 16.2% of the total deferrals.Conclusion:  Ensuring the confidentiality of history taking and examination of donors will help them to answer the questions honestly and to curb the barriers that impede the donation. Defining and educating the donor selection criteria to the community by the medical professionals and awareness and self motivation from the donors are the key factors behind achieving cent percent acceptance of blood donors.
