Why should blood not be frozen?
Blood should not be frozen because the process of freezing and thawing can alter its components, making it unusable for transfusions. Blood is made up of cells, proteins, and other components, and they react differently to the freezing process.
The proteins in the blood can form into clumps, which can clog narrow blood vessels and impede the flow of blood to the organs. Freezing can also cause red blood cells to break down, leaving the blood with a decreased oxygen-carrying capacity.
Additionally, some antigens on the cell surfaces can be altered during the freezing and thawing process, making it incompatible with the recipient’s blood type and leading to serious complications. Freezing can also destroy platelets, white blood cells, and other components of the blood, which can lead to infections, a weakened immune system, an increased risk of clotting, and other potentially fatal problems.
How long does frozen donated blood last?
Frozen donated blood can last at least 10 years when stored properly. The United States Food and Drug Administration (FDA) sets the expiration date for donated frozen red blood cells as 28 days, which is the same as the expiration date for whole blood donations.
Whole blood donations are stored as components and can last up to 42 days. After the red blood cells expire on day 28, the remaining components (i. e. , platelets, plasma) can be stored for an additional 14 days, bringing the total storage time to 42 days.
However, Rh null erythrocytes, which are blood rations used to treat severe anemia, can be stored for up to 10 years. Additionally, frozen plasma can be stored for up to 1 year. It is important to store donated blood at appropriate temperatures to ensure its viability and safety for transfusions.
Therefore, frozen donated blood can last at least 10 years when stored properly.
