DNA Paternity Tests with two completely different results?

Q: I took a home paternity test without the mother and it showed I was not the father, not even close. Then I took another home paternity test this time with the mother and her doing the swabbing and the test came back with the baby having a completely different DNA and this time I was the father. Curiously, Both tests show that the baby has the same Mother but on one I am not the father. How could this happen? I called both companies and they said that a different child must have been swabbed and they asked if the baby had a sister, she does but I was there when she was swabbing the baby I don’t know how she could’ve pulled that off. Any ideas?

A: Aside from a chance of a lab error, you or the baby may be Chimera. This means you are carrying two different DNA strands. This happens in fraternal twins when one fails to develop in utero, and is absorbed into the body of the other twin. Most often, this manifest itself with the child being born with an extra leg, but there was a woman in 1994 that learned she was not the mother of her own children.

As for you, a certified clinic might be best, but understand that this grants you no legal rights to the child. It only acknowledges that you are financially responsible. You have no rights to see the child, or any say in how the child is raised. You voluntarily gave up that right when you had sex with a woman you were not married to, and ignorance of the law is not a defense.
You need to clarify whether or not you are the father, than file for reestablishing your parental rights, and establishing your support obligations.
