vWF is a protein that helps platelets stick together and stabilizes Factor VIII. A level above 70% (up to 180%) is normal and indicates adequate primary hemostasis.
A vWF level between 50-70% is borderline. This dog may have mild von Willebrand disease (vWD) and could experience prolonged bleeding after surgery or trauma. Many dogs with borderline levels lead normal lives without noticeable bleeding.
Your vet may recommend a buccal mucosal bleeding time (BMBT) test. If surgery is planned, cryoprecipitate or desmopressin (DDAVP) may be used pre-operatively to reduce bleeding risk. Avoid NSAIDs.
Canine vWF antigen: 45% (Low, Borderline)vWF is a protein that helps platelets stick together and stabilizes Factor VIII. A level above 70% (up to 180%) is normal and indicates adequate primary hemostasis.
No action needed. Your dog has normal von Willebrand factor levels.
Canine vWF antigen: 95%Elevated vWF is an acute phase protein and rises with inflammation, stress, surgery, or neoplasia. It is rarely a problem in itself but can be a marker of underlying disease.
Your vet may investigate the underlying cause of inflammation or stress. No specific treatment is needed for the elevated vWF itself.
