Let's skip over the fact that you can't get dna from mature red blood cells
and pretend for a moment that you can.
Why would you even consider that red blood cells of different minor types
could be created by cells with the same dna profile?
Think about it.
Your hypothetical dna test is redundant in this instance.
The fact is he has the red blood cells of two individuals in his system. He
needs to explain it. There are explanations; surgery, chimera,
maternal/fetal transfer; he needs one quick.
If he is innocent he should demand to be regularly tested and he will
continue to test positive and be cleared. If he is guilty then you'll see
him question the test and the labs and keep his blood to himself. Time, not
a dna test, will make the answer clear to everyone.
