Con: you may have to retest if they don't get the threshold of fetal cells in your blood that they need. I had to do the test 3 times for this reason!
Pro: you know the statistical probability of having a baby with a chromosomal issue (test is not a definitive, just a probability).
Pro: you find out the gender earlier than the usual 19-22 week time frame, and it is 99.9 percent accurate (as opposed to relying on the ultrasound tech).
I refuse the test every time it is offered now. I got a false positive with my first and the drs tried their best to convence me to abort and got mad when I would not. My daughter had none of what they said and I do not want to be in a similar situation. I would rather just find out when baby comes.
I didn't even know about this test or any others, the only one I knew about was the amnio one. When my Dr started to ask about testing I didn't even give her a chance to tell me about these others, I right away just said I didn't want any tests. I already have a special needs child and know I have a high chance. But I still find myself worrying about it, I don't know why maybe I just don't feel like I would be prepared if this baby has a different disability than my son. I am now feeling like I should have done it to prepare myself, and finding out the gender early would have been nice.
I had it done, but I wanted to know to be prepared if there was a possibility. I am not a big fan of surprises. I also got to find out that I was having a boy at 11 weeks.
This test seems to have ALOT of false positives. My Dr asked me if I planned on aborting if the baby tested positive for down syndrome. I said no I will keep and love my baby no matter what. He said there's no need to test then. I couldn't agree more. I don't see a reason to put yourself through the added stress :)
