The revascularization vehicle volunteered to show blood, but did not receive the qualified notice on the fourth day. What happened?

This is a matter of working procedure. The blood donation car volunteered to donate blood, and on the fourth day, due to work procedures, it did not receive a qualified notice. Blood donation refers to the voluntary donation of whole blood, plasma or blood components by blood donors. These blood are usually stored in blood banks and kept by medical units, blood stations or the Red Cross for those who need blood transfusion. Compared with paid blood donation, the blood quality of unpaid blood donation can be guaranteed, which is beneficial to the health and safety of the recipients.
