Red and white blood cell replacement in the body takes eight weeks.
It is very safe to donate.
When feasible, recipients only receive the specific blood component they require. Whole blood is never given.
Before a donor is approved, a complete medical history is obtained. The donor's ability to donate blood without endangering their own health is then determined by testing a small sample of their blood. You might require a more thorough evaluation of your height and weight if you are under the age of 18.
Different transfusion procedures replace various blood cells or blood constituents. Clotting issues are improved by one kind of transfusion.
The standard donation is one pint. Preservatives and anti-clotting chemicals are added to a plastic bag that is used to seal the blood.
The FDA controls the procurement, holding, and distribution of donated blood.
