I was just in to see my GP with results from my NT scan and blood testing. She said I have a 1:142 risk of Trisomy 18, with more testing to come(amnio I'm guessing?). Not sure what to think about this? My last pregnancy was completely normal and I have no history of genetic disorders. I'm 23 years old, normal weight. She also said I have low Papp-A (not sure of the exact number as she didn't give me my page of results) and then went on to say I have a dysfunctional placenta. She said she's concerned but can't say for sure obviously what the outcome will be. She added that even if the baby turns out negative for T18, I'll still have to be closely monitored because of the placenta. Anyone have any experience with any of this? She wasn't clear on what I need to do or not do or if I need to be worried!
Thanks for any help!
