I don't understand how it works but that is the info I found on it.
This prenatal paternity test uses only the mother's blood - and samples from the alleged father(s) - to determine the paternity of the child as early as 13 weeks into the pregnancy. No blood is taken from the alleged father(s).
Yes it called the non invasive paternity test that they say is 100% accurate but I am a lil skeptical
What test are you talking about that is non-invasive? Are you sure it is to determine paternity?
