What happens if PAPP-A levels are low during pregnancy?

Question

What are the potential consequences or complications if a pregnant woman has low PAPP-A levels?

Answer 1

I had a low PAPP‑A result come back with my first trimester bloods too and it scared me at first. My midwife explained that it can sometimes mean the placenta doesn’t work as efficiently, so they gave me a few extra growth scans later on and kept an eye on my blood pressure. In my case everything turned out fine – my little boy was born at 39 weeks weighing just under 3 kg and perfectly healthy. Some mums with low PAPP‑A do end up with smaller babies or get induced a bit early, but a lot of them have very normal pregnancies. There’s nothing you can really do to change the number, just eat well, rest, and go to your appointments so your team can monitor you. It’s more of a heads‑up for them to watch you a bit closer, not an automatic problem.
