Biology/Answered Question

Expert: Walter Hintz
Subject: Blood Banks - Storage Media.
Question: Dear Prof Walter

http://en.wikipedia.org/wiki/Blood_bank

As mentioned, "Routine blood storage is limited to 21 days at 1- 6C when treated with acid-citrate-dextrose (ACD), citrate-phosphate-dextrose (CPD) or citrate-phosphate-double dextrose (CP2D) and 35 days when treated with citrate-phosphate-dextrose-adenine (CPDA1) (5 weeks for WB, 6 weeks for RBC), and involves refrigeration but usually not freezing."

Does it mean that within 21-35 maximum days period if the blood donated are not being transfused to a receiver matching blood group, then the Blood donated by the Blood Donor will be no use ?

Thanks & Regards,
Prashant S Akerkar
Answer: Hi Prashant
 Yes! Outdated blood is not used for transfusions. It can be used in the making of blood Agar that is needed for microbiology diagnosis
