ACD was developed into CPD (citrate-phosphate-dextrose) in 1957, a version with phosphate added intended to reduce phosphate leakage from red blood cells. It does not improve shelf life appreciably, but patient recovery is improved.
ACD was transformed into CPD (citrate-phosphate-dextrose) in 1957, a version with phosphate added to minimize phosphate leakage from red blood cells. It does not significantly enhance shelf life but enhances patient recovery.
