Cryoprecipitate, also called "cryoprecipitated antihaemophilic factor", "cryoprecipitated AHF", and "cryo" for short, is a frozen blood product prepared from plasma. To acquire cryoprecipitate, the fresh frozen plasma should be centrifuged and the precipitate should be collected. It is often transfused as a four to six unit pool instead of as a single product. Many uses of the product have been replaced by factor concentrates, but it is still routinely stocked by many hospital blood banks.
