Can whole blood be kept in freezer?

Whole blood should not be kept in a freezer for long-term storage, as freezing can cause the red blood cells to rupture, leading to loss of functionality. Instead, whole blood is typically stored at refrigerated temperatures (about 1-6°C) for a limited time. For long-term storage, blood components like red blood cells, plasma, and platelets can be frozen under specific conditions, but this requires careful handling and processing. Always follow established guidelines and regulations for blood storage.
