Q&A: is it possible for a DNA test to be wrong and the child look just like the alleged father?
Question by : is it possible for a DNA test to be wrong and the child look just like the alleged father?
Is it possible to have a swab DNA test done and it come back that the alleged father is not the father. However my child looks just like him, as if he spit out. Can someone please help put a stop to my madness.

I think that it is highly ulikely, but i did see a tv show of a women who had several kids and her dna did not match any other her kids. She was accused of not being the mother and threatened to have the kids taken away from her until she was pregnant again and they watched her give birth to the child and then tested the newborn baby and the dna did not match the mother but obviously she was the mother.. i’m sure possibly it could happen with a father too, but probably super super rare.

there’s always a chance for DNA test to gives the false output. The two main types are:
1) technological error, namely that the test somehow interprets DNA wrong. But this is a very rare error, only like…0.01% of getting it.
2) biological error. This relates to the concept of chimera, where apparently, if you take DNA from one tissue, that DNA may change if you take DNA from another tissue of the same person. This is first observed in moms, where in the past, moms have been falsely accused of not being the real mom of the child, despite the fact that she is. This is now often corrected by taking multiple samples from different tissues of the same person.
So in ur case, you should consider the following:
1) is ur DNA test done at a reputable company? (and by reputable, i mean, does people actually know the company? just because the company claims it’s good don’t mean it’s good! you should check the popularity of that company)
2) is the DNA sample collected from multiple samples? (i.e. if it’s just from mouth, it may not be enough)
3) is the DNA sample handled by professionals? (i.e. not just some college-graduates looking for intern work, but actually done by reputable scientists)
