Just re-checked her posts to see if it is easy or hard to search by user name, and it turns out that she tested with Ravgen and the DDC and their tests both confirmed each other's results. But Ravgen was her pre-natal test and the DDC was post natal. Sorry to get it backwards.
A poster with the user name of jazzyjay123 posted relatively recently that her post-natal test confirmed her prenatal test done by the DDC.
Hi, momto, women have written in on this site saying that they got tested again and confirmed the results they got from a prenatal test, the most recent of these had tested with the DDC. It's worth noting that once their worries are relieved, women usually stop writing in -- the fuel for taking the trouble to write in to this community is anxiety, and once the woman has had the baby and is busy with it and the paternity question is resolved, it's rare for her to write back either to say all is well or to say the opposite. (Actually, they probably would be more likely to write back to say the opposite if that is what happened, so in a way no news is probably good news.) But someone did take the trouble in the last 7 months or so to write in and say she had had her prenatal test confirmed.
