I had a DNA test done to establish maternity for my son, the test came back that the man I had tested was not the father. Me and the man got a retest because we could not believe the results and sure enough the 2nd test said he was the father. I'm so confused. When I asked the facility they said the gel they used had expired. Shouldn't I get some of my money back? What would of happened if I hadn't gotten a retest?

my best friend needs to get a DNA test done on his 2 kids. His ex wife is taking child support from him and she cheated numerous times on him while they were together. She lives in Philadelphia and he lives in California. How can he get a dna test done? He doesnt have the money to hire a lawyer.

would i need to take a dna test to see what every nationality you have in you and how much you have?? would it cost money and where would i go to do this?
