Following a 500 ml (+/- 50 ml) whole blood donation, lost volume is replaced within 2-4 hours as fluid is recruited from the interstitial tissue space. Red cell mass is replaced within 2-4 weeks by the bone marrow, if adequate iron stores are present.
Following volunteer whole blood donation, red blood cells (liquid) may be kept at 1-6 degrees C for up to 42 days, depending on the additive solution used. Rare units of red cells may be frozen for up to 10 years. Platelets have a shelf-life of 5 days, and must be stored at room temperature (20-24 degrees C) on a platelet rotator. Fresh Frozen Plasma (FFP) must be separated and frozen within 8 hours following collection, and may be stored for 1 year at -18 degrees C.
The body immediately works on restoring blood that was donated. Fluid stored in the tissues returns to the blood stream. Red blood cell production speeds up. A donor's blood volume is restored within a few hours. Red blood cells replace themselves more slowly, but are restored within the interval between donations.
up to 48 hours for plasma to be replaced. 4-8 weeks for red blood cells to be replaced.
