Description: Ans. is `c' i.e., 21 days The recommend temperature for storage of blood is 1-6degC. Actually blood can be stored for more than 21 days, depending upon the type of additive used. "Routine blood storage is limited to 21 days at 1-6degC when treated with acid-citrate-dextrose (ACD) or citratephosphate-dextrose (CPD); and 35 days when treated with citrate-phosposphate-dextrose-adenine (CPD-A); and 42 days when treated with saline-adenine-glucose-mannital (SAG-M)" So, correct answer of this question can be: 21 days (we have only this one in the options) 35 days 42 days (This is the best answer because SAG-M is the routinly used additive these days). Platelets are stored at 20-24degC for 3-5 days
