My husband took 2 different DNA test. One was done by us and the child it returned a negative result. The second test was done by him and the child and mother, this time the test was positve. However the numbers from the second test did not match the numbers on the first test for the father or child. is this possible?. what happened?

My crazy mother is concerned that there is a ridiculously small chance that my adopted brother might be dating someone that may be related to him without knowing it. My brothers parents were Irish and the girl he is dating is Irish, so she automatically assumes the worst and thinks that they could be related. Is there some sort of DNA test that can be done to see if by any chance they might be related without having to tell them? Can you collect hair or something and send it to someone?

My father died when i was 2, now my mother tell me that a girl i know maybe my sister by my father. I was wondering if a dna test would show if we were.

My friend thinks he might be the father of his ex girlfriend child but she wont let him take the DNA test but now she is with someone else and the child has her last name of her husband?

This girl is claiming that i got her pregnant. There is a good chance that i am not the father, but i need to be certain. Where and how do i take a DNA test, and how much does it cost?

Yes, I am pregnant and I am going to need one. Please hold any rude remarks, I am just wondering where in the world someone would go to get a dna test. I am 3 months pregnant, is it something that could be done now? And what is the average price range?

Im an aspiring entreprenuer, and I was recently researching the cost of a personal dna test due to a friends situation, and an idea came to me. I could dna test at home for a competitive price... is it possible to set up a lab at home?
