Packed red cells are stored in:: (A) SAG-M solution, (B) PCR-F solution, (C) MED-R solution, (D) DAM-P solution
Answer is A. Packed cells are stored in a SAG-M solution (saline–adenine–glucose–mannitol) to increase their shelf-life to 5 weeks at 2–6 deg C. (Older storage regimens included storage in CPD – citrate–phosphate–dextrose solutions – giving cells a shelf-life of 2–3 weeks).
