Abstract
Conclusions
Undecalcified hemophilic plasma shows markedly less loss of prothrombin activity on storage than does oxalated plasma. 2. Aluminum hydroxide removes component B from native hemophilic plasma. 3. The prolonged prothrombin time in stored human plasma is strikingly shortened by the addition of defibrinated plasma treated with aluminum hydroxide. This proves that the delayed prothrombin time in preserved plasma is not due to an alteration of the fibrinogen.
