Hi,

I have also been reading this thread with interest as my PAPP-A on the nuchal test was 0.24 MoM and the risk of Downs was 1:54 (amnio results were all clear). I'm now 37 weeks and all seems to be well, although I have been measuring small for dates all along. I have been having growth scans every 4 weeks for this reason but my OB was not at all concerned about the low PAPP-A. The last scan 3 weeks ago showed that the baby was on about 40th centile for estimated weight, which I was very happy about. Still have a really small bump though! I'm having another scan next week which will hopefully show that baby is still growing well, otherwise I might have to have an induction.

EveningRose, I was the same as you, stressing out because I was measuring way behind for fundal height, not gaining weight and the OB saying I was too small and would need US monitoring. The 2 week wait leading up to the last growth scan was horrible! Anyway it turned out there was nothing wrong so all that worry was for nothing. I hope your scan on Wednesday went well, and showed that your baby is fine.

Flowerchild, thanks for your comments about the association between low PAPP-A and placental function, I have been reading about this. I had a retroplacental haematoma and bled all through the first trimester, and wonder if this means that the development of the placenta was affected by this.
