Regular voluntary unpaid blood donation assures safe blood supply in association with minimum infection transmission.

Chi-square test of independence/ Fischer’s exact test were applied to assess statistical significance.


In medical group 5/21(23.8%) voluntary regular donors were recorded. In non-medical group, voluntary regular donors were found to be 8/30 (26.6%) (p>0.00). Medical students most commonly 15/21 (71.4%) donated blood voluntarily in a camp while non-medical participants frequently donated blood as replacement donors 13/30 (43.3%) (p>0.00).
