Well I would not take any blood in this instance since it is living tissue and you can have same problems like with organs transplantation, and blood mostly consist of blood + toxins + viruses etc. Also you never know if blood donator wasn't smoking, taking drugs, abusing alcohol, and I know a lot of stories of people getting some viruses by having blood transfusion. Also from what I read people can get back to health much faster without transfusion and instead using synthetic blood.
