Yes, the blood bank will inform you whether it is unqualified.

If there is an infectious disease, the CDC will call you. Attention, this is the CDC, not a blood station.

But this doesn't mean that you are completely healthy, because some problems can't be detected by blood tests. Blood stations mainly detect the source of blood-borne diseases, not physical examinations.
