Final answer:
The shelf life of whole blood collected in CPDA-1 is 35 days, as CPDA-1 serves as a nutrient-preserving and anticoagulant solution, extending the usability of red blood cells.
Step-by-step explanation:
The shelf life of whole blood collected in citrate-phosphate-dextrose-adenine (CPDA-1) is 35 days.
CPDA-1 is a preservative solution used in blood transfusion services which provides necessary nutrients to red blood cells and prevents clotting. By using CPDA-1, the longevity of the packed red blood cells is extended, compared to other preservatives which may have shorter shelf lives.
CPDA-1's ability to maintain the viability and function of red blood cells makes it a preferred choice in many blood banks and healthcare settings, allowing for extended storage and better management of blood supplies.
