5 severe haemophiliacs were infused with cryoprecipitate prepared by the continuous
thaw-siphon technique, with cryoprecipitate prepared by overnight thawing and with
intermediate-purity factor VIII concentrate. All 3 preparations gave a similar mean
half-life for coagulant factor VIII of approximately 10 hours. The immediate recovery
of this activity was similar for the 2 cryoprecipitates, but higher for the purified
concentrate.
