After donating blood, I received a text message from the blood bank saying that I passed the test. Does that mean my blood can be used?

It can be considered that after receiving such a short message, you can be sure that your blood is qualified and can be used for blood transfusion in medical treatment. The previous text message can only show that the plasma is still in transit and has not been tested. For yourself, the greater significance is that you can prove that you are healthy and have no disease, and you are really looking forward to adoption.
