Can Blood Transfusions or Bone Marrow Transplants Alter Your DNA? Apparently, It CAN!
"As a DNA analyst, we know that blood transfusions can cause us to see a mixture of DNA profiles in the blood sample for anywhere from 30 to 60 days after the transfusion. It is pretty rare that we actually see this, but it can happen.

As for bone marrow transplants - they can cause two different scenarios. They can cause a mixture of DNA because you have the persons own DNA, as well as the DNA being produced by the tranplanted bone marrow. Over time in these situations, if the new bone marrow ends up completely taking over for the persons own bone marrow - it can actually change the DNA profile that would be seen in the blood. So the person would have one DNA profile in their skin cells and a different profile in their white blood cells. Again, this is pretty rare, but is known to happen."

Sounds like an unexpected twist to a murder mystery.

I always thought that the blood or organs transplanted into another person would keep its original DNA profile since it does come from another person, if so there would be a mixture of DNA in the persons body, makes sense.
