How long does it take for blood to expire

Answer 1

Blood does not technically "expire," but it does have a shelf life. Whole blood is typically stored in a blood bank for up to 42 days, while packed red blood cells can be stored for up to 42 days as well. Platelets, on the other hand, have a much shorter shelf life and are usually stored for only 5 to 7 days. Plasma can be frozen and stored for up to one year. It is important to note that blood products may have different expiration dates depending on the specific storage conditions and regulations of the blood bank or facility.
