Will the blood collected from the blood donation car be tested again when the hospital takes it back for use?

Check whether there is anything wrong with the blood. Check it carefully.

If you are healthy or unhealthy, you will send a short message to the blood donor to inform you that your blood is healthy or unhealthy.

Not necessarily blood, blood transfusion containers, blood obtained illegally in some small cities. There are also blood transfusion containers sold through bad channels, which are also very unsanitary. The blood collection vehicles of the Red Cross on the street are all disposable containers, which are very secure. You should rest assured of these.
