How is donated blood stored?

Whole blood is usually stored in a blood bank, at temperatures between 2 degrees Celsius and 6 degrees Celsius (36 degrees Fahrenheit and 42 degrees Fahrenheit) for a maximum of 42 days. Some blood centers may use a special additive solution to extend the storage time to 49 days.

Blood components have various storage conditions and durations:

Red blood cells (RBCs): RBCs are stored in a preservative solution at 4 degrees Celsius. They can last up to 42 days under controlled conditions.

Plasma: Plasma is the liquid component of blood. It can be stored at -20 degrees Celsius for up to one year, or at 4 degrees Celsius for up to 5 days.

Platelets: Platelets are stored in a special storage device at 20-24 degrees Celsius and agitated gently. They can be kept for up to 5 days.

Cryoprecipitate: Cryoprecipitate is a component of plasma that is rich in certain clotting factors. It is frozen and stored at -18 degrees Celsius or below. It can last up to 1 year under proper storage conditions.

Proper storage conditions, including temperature and agitation (if required), are essential to maintain the viability, functionality, and safety of donated blood and its components.
