Transfusions and DNA Identification
Name: Ingrid C.

Similar to the DNA testing questions, I want to know if a
person gets a whole blood transfusion and then dies the next day of some
horrible crime (Nothing to verify who the victim is but the DNA), would
the DNA show up as the donors or not? And since the red blood cells have
no DNA, what about the white blood cells?
The DNA in the white blood cells might confuse the issue. However, this can
be avoided by choosing a sample other than blood to test. Many DNA tests are
taken from cheek cell swabs.
