Blood Storage: Time Limit & Transfers?

In summary, there is a time limit before blood starts to go bad, which varies depending on the type of blood. Whole blood has the shortest storage time, while plasma and platelets can last longer. The storage times also differ based on the type of anticoagulant-preservative solution used. Frozen RBCs can be used up to 10 years after being frozen, and platelets typically only last 5 days if left at room temperature.

How long can blood be stored for until it's no longer usable is there a length of time after which its stored where it can no longer be transferred into someone? why/why not? thanks

There is a time limit before it starts to go bad, but I don't remember those limits off the top of my head. You could probably find out the information from a site from a blood bank or such. The storage times also differ based on the types of blood. Whole blood has the shortest storage time, while plasma, platelets, etc., last longer.

A unit of whole blood/prepared RBCs could be stored for 21 to 42 days but that depends on the type of anticoagulant-preservative solution you use. You can actually use frozen RBCs up to 10 years after they have been frozen. Platelets usually only last about 5 days if left at room temp and have to be agitated continually.
 

1. What is the recommended time limit for storing donated blood?

The American Red Cross recommends a maximum storage time of 42 days for donated whole blood and 5 days for donated platelets.

2. Why is there a time limit for storing donated blood?

Donated blood has a limited shelf life due to the fact that red blood cells have a short lifespan and can only be stored for a certain amount of time before they deteriorate. Additionally, the risk of bacterial growth and contamination increases the longer blood is stored.

3. Can blood be transferred between blood banks or facilities?

Yes, blood can be transferred between blood banks or facilities as long as proper storage and transportation guidelines are followed. This ensures that the blood remains safe for transfusion.

4. Is there a difference in storage time limits for different blood components?

Yes, there are different storage time limits for different blood components. Whole blood has a maximum storage time of 42 days, while red blood cells can be stored for up to 42 days and platelets for up to 5 days. Plasma and cryoprecipitate have longer storage times, up to 1 year when frozen.

5. What happens to blood that is not used before the time limit expires?

If blood is not used before the time limit expires, it is discarded. This is to ensure the safety and effectiveness of the blood for transfusion. However, in some cases, blood may be used for research or other medical purposes before the expiration date.
