A blood donation is when a healthy person voluntarily has blood drawn. The blood is used for transfusions or made into medications by a process called fractionation.
In the developed world, most blood donors are unpaid volunteers who give blood for a community supply. In poorer countries, established supplies are limited and donors usually give blood when family or friends need a transfusion. Many donors donate as an act of charity, but some are paid and in some cases there are incentives other than money such as paid time off from work. A donor can also have blood drawn for their own future use. Donating is relatively safe, but some donors have bruising where the needle is inserted or may feel faint.
The amount of blood drawn and the methods vary, but a typical donation is 500 milliliters (or approximately one US pint)[1] of whole blood. The collection can be done manually or with automated equipment that only takes specific portions of the blood. Most of the components of blood used for transfusions have a short shelf life, and maintaining a constant supply is a persistent problem.
In Auckland, BillaG organise "Blood Balti" which is purely a humanitarian activity. This must be praised by all and there is a lesson too for us which is "Every person can make a change provided he or she is willing to ADD something to the society from which we have gained but not returned back anything yet".
