A method is described for preparing fibrin glue from fibrinogen obtained by double cryoprecipitation of plasma collected by plasmapheresis. Plasma (average volume, 528.8 +/- 86 mL), collected from 12 plasmapheresis donors was cryoprecipitated twice. When the cryoprecipitated pellet was resuspended in 0.5 to 2 mL of saline (total volume of saline-resuspended fibrinogen: 5 mL), the average yield of fibrinogen was 78.4 +/- 18.3 mg per mL. This is comparable to commercial preparations, is suitable for clinical use, and offers greater safety at a reduced cost.
