Bleeding Score
This is a quantitative assessment of bleeding risk based on history, and can predict the likelihood of VWD Type I.
- ASH Pocket Guides App contains several calculators including the bleeding score calculator

Abnormal PT/INR or PTT
- 1:1 mixing study (50/50 mixing study, circulating anticoagulant)
- Liver disease
- Elevated PT only
- Vitamin K deficiency
- Warfarin
- Dietary habits
- Antibiotic use
- Malnutrition
- Increased gut motility
- Deficiency or inhibitor of factor VII
- Lupus anticoagulant (rarely)
- Vitamin K deficiency
- Elevated PTT only
- Heparin
- Deficiencies of factor VIII, factor IX, factor XI, factor XII, or inhibitors.
- Not associated with increased bleeding risk: Prekallikrein deficiency, high molecular weight kininogen deficiency, factor XII deficiency
- von Willebrand disease
- Lupus anticoagulant
