The procedure of organ donation is much more complicated than commonly thought. First of all, we need to sign an agreement when we are alive. This agreement is called China Voluntary Letter of Human Organ Donation. There are many things to be filled in the agreement, but this is only the first thing to do. After the agreement is handed in, all localities will send people from the hospital to evaluate your body and confirm that your body meets the criteria for organ donation. The above two steps are the preparation procedures before organ donation, and the subsequent procedures will not begin until the organ donor reaches the time of donation (usually death). Although there are living donations, the number is very small. Assuming that the organ donor has died, then the family members have to sign a registration form for organ donation, and then the experts can start transplanting organs and finally complete the organ donation work. In short, the whole process is quite complicated.
