All of the following are true about anticoagulants except:: (A) Maximum storage with CPDA-1 is 35 days, (B) Maximum storage with SAGM is 42 days, (C) Sodium diphosphate helps in synthesis of ATP, (D) Citrate Prevents coagulation by chelating calcium
Answer is C. Whole Blood Anticoagulant used Maximum storage ACD/CPD/CP2D 21 days CPDA-1 (citrate phosphate dextrose adenine) 35 days SAGM (Saline adenine glucose mannitol) 42 days Actions of ingredients of Anticoagulant solution Glucose - ATP generation by glycolysis Adenine -Synthesis of ATP - Increase shelf life of RBC to 42 days Citrate - Prevents coagulation by chelating calcium Sodium diphosphate - Maintain optimum pH
