Hemophilia A

Monday, September 18, 2017

(NJ) Hemophilia A (Factor VIII deficiency) was identified as the cause of non-traumatic hemorrhage in a 16-week old male Pitbull mix puppy from NJ. The puppy had a history of shifting leg lameness, and had subcutaneous and intramuscular hematomas at presentation. An in-house APTT and PT were normal, however testing at the Comparative Coagulation Lab revealed a specific prolongation of APTT and severe Factor VIII deficiency (FVIII =1% of normal) thereby confirming a diagnosis of hemophilia A.
