Cryoprecipitate must be stored frozen at -18°C or colder, typically at -30°C. This is because cryoprecipitate is rich in labile clotting factors, particularly fibrinogen, Factor VIII, von Willebrand Factor (vWF), and Factor XIII. Freezing at very low temperatures preserves the activity of these proteins for up to one year from the date of collection of the original plasma. Once thawed for use, it must be kept at 1-6°C (refrigerated) and should be transfused as soon as possible, generally within 4-6 hours, because the factors begin to degrade. Some protocols allow for storage of thawed cryoprecipitate for up to 24 hours if maintained at 1-6°C, but this varies by regulatory guidelines. The strict temperature control is essential to ensure that patients receive a therapeutically effective dose of clotting factors when treated for conditions like hypofibrinogenemia.
