Miasmomma, if you tested and got an inclusion, it's hard to see what the problem is. We have only had one poster who has written into this community that had a problem with the DDC, and her problem was an exclusion (he had been the only guy she was sleeping with and they said he wasn't the dad) not an inclusion. A false positive is a lot harder to get than a false negative, at any lab with any test, and the DDC is one of the best in the world for this kind of testing. A lot of women who do prenatal DNA tests make two mistakes. Their first is, they only test with one guy, so there is no test that says "not him" to back up the other guy's test that says "this is the one." Then they start thinking maybe the answer they got was wrong. If they had had two guys' tests, one would support the other. The second mistake is, and they stew in their own juices and freak themselves out so much that they don't want to believe any test about anything, or anything else. It's almost like a fun hobby, to fret and fret over this fake concern. Try to address your real source of worry (believe me, it's not actually "who is the baby's daddy" -- look for something about having a baby that makes you anxious deep in your heart) and your worry about paternity will fade away as you address the real issue.
Good luck to you.
