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.
Potential donors are evaluated for anything that might make their blood unsafe to use. The screening includes testing for diseases that can be transmitted by a blood transfusion, including HIV and viral hepatitis. The donor is also asked about medical history and given a short physical examination to make sure that the donation is not hazardous to his or her health. How often a donor can give varies from days to months based on what he or she donates and the laws of the country where the donation takes place. For example, in the United States donors must wait 8 weeks (56 days) between whole blood donations but only three days between plateletpheresis donations.
But Is It Possible for Diabetics to Donate Blood. (It is from http://www.diabetes-kidney.org/)
We all know that patients with heart disease, hepatitides, infectious diseases and AIDS are not allowed to donate blood, then what about diabetics?
For the question, all countries require that your diabetes is well controlled, you are not suffering from any acute disease and feeling well. Due to the risk of CJD, most people who have used beef insulin are deferred from donating blood.
Are those on insulin injection allowed for blood donation?
Generally speaking, those on insulin injection for reducing blood sugar level are not allowed to donate blood. That's because the compositions of the medicines remaining in the blood is not good for the receptors.
Comparatively, for those who are controlling their disease through dietary therapy and exercise, if there exist no diabetic complications such as eyes, kidneys and their blood vessel related problems, blood donation is allowed.
So if you have diabetes, You can not Donate Blood.
