I am 18 weeks pg and had the amniocentesis on Monday, was expecting the FISH (rapid results) by yesterday. I spoke to the geneticist and he said there were "no fetal cells" visible in the sample, and that it might not be possible to get any rapid results in which case we would have to wait for the full results which will take at least 2 weeks. But that might not work either.
He told me to phone back today as there might be some progress in the culture, but didn't seem too optimistic.
(Btw I am not in the UK so the usual NHS procedures don't apply, I am seeing an ob-gyn and she and another ob-gyn carried out the amniocentesis at hospital.)
It seems people sometimes have to repeat the whole procedure as 1/100 times the culture doesn't work - it seems, after a bit of googling (!) this can be due to contamination of the fluid with blood. Since they managed to scratch my tummy and draw a tiny bit of blood during the ultrasound (the needle must have been poking out slightly) I am now thinking maybe a bit of my blood got into the amniotic fluid and messed up the sample. The scratches were only noticed after the whole process was over.
I really don't want to go through the whole thing again because of the obvious risks and strain on the body but then again... want to know one way or another if the baby is healthy. We did the amnio on the basis of age (almost 40) and 2 previous mcs in the past year incl MMC. My doctor suggested I skip the screening tests (except for NT, which looked perfectly fine) and go straight to the amnio given that we wanted a definite result.
I guess I was just wondering if anyone had been in the same situation and what you decided to do as me and DH are feeling a bit confused and frustrated at the moment. TBH we weren't aware this "failure" could even happen! Thanks.
