Control were those patient who were admited for any surgical procedure in ENT without history of nasal bleeding.

Results: In patients with epistaxis blood group O was most common (45%) followed by B(25%) then A (15%)and AB(15%).Control group showed group O(35%)and A (35%) equal in number followed by group B (23.33%)and group AB(6.66%). Thus expression of blood group O in patients with epistaxis was significantly more than the control group.
