I'm sure if the PappA is v low and hcg high that can be an indicator of downs BUT please remember that lots of women can get poor results and go on to have healthy babies. I had a 1 in 7 result, my hcg and Papp results were double the level they should be, I chose to have a cvs and my baby is fine. 1 in 10 actually means there is a 90% chance everything is okay? It is just a statistic however I do understand how you feel as I've been there but I think you should take comfort in the additional tests you've had but others are right, the only way you will get 100% guarantee is through a diagnostic test. These tests are always a worry as you always worry 'what if our baby is the one'? Sometimes I wish I'd never had the nuchal test but what I would also say is if you were to do a diagnostic test and you didn't get the result you want, what would you do as that may help you decide whether to be reassured by what you've been told already or whether you need a 100% guarantee. Either way, I wish you a happy, healthy pregnancy and good luck in whatever you decide as I know how you feel x.
