. The pH of the freshly collected blood in CPD solution bag is –
Correct Answer: 7*4
Description: Answer is option 3,ph7.4 donation of whole blood is most commonly collected in acidic citrate-phosphate-dextrose (CPD) variants with pH 5.2 to 6.2 as anticoagulants. Previously, we have shown that the initial pH after red blood cell (RBC) preparation can have an effect on RBCs during storage. First, we investigated the effect of the pH of the anticoagulant on RBCs. Second, we investigated the possibility of decreasing the pH of our new additive solution (AS) phosphate-adenine-glucose-guanosine-gluconate-mannitol (PAGGGM) from pH 8.2 to 7.4 in combination with an anticoagulant with a physiologic pH.
