can blood transfusions change or enhance your dna?

Answer 1

Good question! If you get a DNA test (from blood) prior to a blood transfusion, you will come out with a test result of only your DNA. If you get a DNA test (from blood) after a blood transfusion, they can detect BOTH your DNA and the DNA of the blood donor as well. It would still be possible to obtain a positive identification of your individual DNA separately from the blood donor.

In about 56 days, the donor's blood cells will be consumed by your body as new blood cells are formed and there would be no trace of the donor's DNA in your blood.

A DNA test taken from a tissue sample (cheek cells or skin tissue) would show your own DNA exclusively and nothing from the blood donor.

Answer 2

No, but it COULD confuse the test results if your blood was left at a crime scene (not to give you any ideas for getting away with murder :-).

Blood cells only live about six weeks and then are discarded by the body. They do not replicate by splitting in half, like most cells; they are created in the bone marrow, and will therefore have your own DNA in them.

So taking a transfusion of blood from, say, an Olympic runner won't give you any permanent ability to run faster than you do now. But it WOULD be possible for you to leave a blood sample with your DNA and the DNA of your blood donor. I'm surprised we haven't already seen Grissom tackling this issue on "CSI," it'd make a nifty twist (especially if they identify the blood DONOR and he turns out to be innocent).

Answer 3

As I understand it, people who have had recent (same day, or day before) blood transfusions prior to a DNA test, can show up two different kinds of DNA on the test, but this is why they ask if you have had any transplants or transfusions recently, when you get your DNA tested. And, if they see two different kinds show up, they will just take another DNA test later (assuming it is for purposes of legal defense or prosecution in a court of law.)

Having said that, some prisoners have been shown to have two different kinds of DNA in their bodies, and this was discovered by such repeated DNA testing. Sometimes, when a woman is pregnant with twins, even fraternal twins which are not identical, one can begin to absorb the other. The person may be born and grow to maturity without suspecting that they contain living DNA from an unborn brother or sister. But the tests can show it.

This may account for some people who suffer sexual feelings and impulses that do not correspond to the gender of their bodies, because of the sex of the DNA in remaining tissues. Someday, we will have prenatal testing and treatments for people with such congenital birth defects, so they do not experience confusion later on in life. It will not be easy, and it will not be inexpensive, but that is better than letting them suffer all their lives long, or assuming it is not a congenital birth defect and trying to change all of society instead.

Answer 4

No,they do not affect your DNA in any way.
However,If you take blood transfusion and immediately take up a DNA analysis,it is likely that your results may be altered because the DNA which you gor from blood transfusion may also be counted in it.
If only RBCs are given in blood transfusion,i.e,Packed red cell transfusion,chances of getting altered results are very less.

Answer 5

The DNA in the blood cells would be different, but not in the rest of your cells. As far as CHANGING or converting your whole genome..No.

Answer 6

hello DNA is not transformable from blood.

Answer 7

No, blood tranfusions cannot change your DNA.

Answer 8

Nope. You can't change your DNA.

Answer 9

Yeah, I became a super hero this way.
