## Abstract

Blood donor deferral is essential for safety. However, it impacts donor recruitment. Therefore, it is of interest to analyze deferral
patterns at a rural tertiary care hospital in North India (March 2018-March 2023) among 45,067 registered donors. 8,159 were deferred
76.4% were temporary (low hemoglobin, recent medications) and 23.6% were permanent (hypertension, diabetes). Notably, 25% of male
deferrals were due to recent alcohol intake. Hence, targeted strategies addressing these causes could improve donor retention and blood
supply stability.
