Hi,
I am pregnant at 40 and have a history of miscarriage because of trisomy 4, so amniocentesis seems inevitable. But I just learned that there is a new blood test (harmony)that gives accurate results ( but my obgyn says not as accurate as amnio) Trying to conceive for 2 years so I am reluctant to take the risk of amniocentesis. Is there anybody in the same situation or have an opinion about this new test? They say amnio has %100 reliability, but in the reports I saw it says this analysis can't find mosaicisms and rare disorders etc. , so it looks like amnio is not %100 either.
