Buccal mucosa bleeding time

icanis
Contributor(s):

Synonym(s): BMBT


Overview

  • Small vessel injury, eg incision in buccal mucosa, plugged by platelets and with minimal need for functional clotting cascade provides assessment of primary hemostasis, ie platelet function.
  • Patients with coagulation defects such as hemophilia A or B have a normal BMBT since the bleeding stops in the expected time owing to the formation of platelet plugs.
  • Note, since the platelet plug is not stabilized by fibrin strands, the incision is prone to re-bleed if traumatized later.
