more or less blood transfusion and dna traces ?

A person have a blood transfusion.
will they eventually cycle out the transfused blood so that they have solely thier dna ,
or will traces of the transfused blood dna still remain in the body years after transfusion ?
and would both dna codes come out within a test? Normal red blood cell have a life span of about 120 days, and do not hold a nucleus, so DNA is extremely minimal. White blood cells, which do own a nucleus, last nearly 10 days. Transfused blood has have most of the white cells taken out, and does not final as long as your own blood when transfused. So the amount of time it would take for the donor DNA to be cleared from the body would be days, not years. I believe that a swab from the inside of the mouth would circumvent any problems involving blood transfusion and DNA, anyway.
If this is a factual question, I will grant a genuine answer. The human body will indeed recycle the blood donation and good posture in mind that the amount of blood surrounded by the average adult's blood stream (approx 9 pints) is moved around all the organs so smartly, your own DNA profile would become obvious inwardly as little as 2 minutes.
