How long can blood stored with Cpda?
When RBC ATP decreased to the level of critical ATP, the time of preservation was considered as shelf life. The results showed that at temperatures from 10 to 33 degrees C, the shelf life of CPDA whole blood ranges from 2.5 days to 18 days, while shelf life of ACD whole blood ranges from 1 day to 13 days.
