Blood storage involves specific conditions to maintain the integrity of its components. Red blood cells are typically stored at 1-6°C for up to 42 days. Platelets are stored at room temperature (20-24°C) with constant agitation and have a shelf life of 5-7 days. Plasma and cryoprecipitate are frozen at -18°C or lower, allowing them to be stored for up to a year. These conditions help preserve the functional properties and prevent microbial growth.
