Question

Blood component with its shelf life?

Plts
PRBCs
FFP
a) Platelets: 5 days, PRBCs: 42 days, FFP: 1 year
b) Platelets: 14 days, PRBCs: 7 days, FFP: 30 days
c) Platelets: 7 days, PRBCs: 35 days, FFP: 5 years
d) Platelets: 30 days, PRBCs: 14 days, FFP: 1 month

Answer 1

The shelf life of different blood components is: Platelets - 5 days, PRBCs - 42 days, and FFP - 1 year (option a). Platelets have the shortest shelf life and are used for their clotting properties, while PRBCs and FFP are used to restore oxygen-carrying capacity and clotting factors respectively.

Step-by-step explanation:

The correct option : a

Platelets: 5 days, PRBCs (Packed Red Blood Cells): 42 days, FFP (Fresh Frozen Plasma) Platelets have a shelf life of only about 5 days because they are delicate and have a propensity to clump together. After donation, platelets are stored at room temperature and are constantly agitated to prevent clotting. The PRBCs can be stored for about 42 days under refrigeration. However, their functionality might decline closer to the expiration date.

PRBCs are erythrocytes that have been concentrated after removal of the plasma and are used in transfusions to restore oxygen-carrying capacity in patients. FFP is plasma that has been separated from the blood and then frozen to keep the clotting factors stable. It can be stored frozen for up to 1 year and is used to treat patients with a deficiency in clotting factors or with massive transfusions.
