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?
