For a detailed history of bleeding, the ISTH Bleeding Assessment Tool (BAT) is recommended [1–3], taking particular note of hemostatic challenges such as dental procedures, surgeries, childbirth and necessary transfusions. Especially males and children can have normal scores even in the presence of an identifiable bleeding disorder [4]. Reference values: Normal range: Men 0-3, Women 0-5, Children 0-2 [5].
