[Bleeding times in haemophilia patients treated with lyophilised antihaemophilic globulin (AHG) (author's transl)].

Tests on 16 patients with haemophilia A confirmed earlier studies that bleeding times may be prolonged after treatment with antihaemophilic globulin (AHG). Despite adequate factor VIII substitution by AHG, treatment effect was unsatisfactory in all 16 patients and there were abnormally prolonged bleeding times after several AHG infusions. But determination of bleeding times after single AHG infusion provides no pointer to possible later problems.
