Can a hospital require families with blood donation certificates to go to the hospital for blood transfusions on the grounds that the blood bank is short of blood? If the blood bank lacks the blood donation certificate, will it be useless?

This situation is called mutual aid blood donation. Generally speaking, there is no need to do this if the blood bank has sufficient blood. However, this is also a very helpless approach. Many people cannot understand it because the blood reserves are insufficient and the inventory is insufficient. The blood can only be used by Manchus for clinical rescue. Therefore, it is recommended that relatives and friends of elective surgery patients donate blood to each other to ensure the stock of the blood bank. This does not mean that blood is not allowed to be used with a blood donation certificate, nor is it a way to deceive the people. Please understand. Support voluntary blood donation more so that we can ensure that more patients who need blood can use blood in a timely and sufficient amount!
