A simple method for preparation of good quality cryoprecipitate.

Production of good quality cryoprecipitate from plasma was achieved, as assessed by quantitating Factor VIII coagulant activity (F VIII C) and Factor related antigen (F VIII R: Ag). The method used resulted in good recovery of FVIII in the cryoprecipitate containing F VIII C: Fibrinogen 0.82 +/- 0.015 IU/mg. The method therefore appears suitable for indigenous preparation of F VIII in standard blood banks as a replacement therapy, which is not expensive.
