Screening results in twins: high risk

[Twinsat42]

Hi
I am 42 and expecting fraternal twins, I have been given high risk DS of 1:100.
My results were;
NT 1.80mm / 1.80mm
Beta hcG free 3.76 MoM
Papp a 2.54 MoM
I’m so worried, and they couldn’t tell me what a ‘normal result was for twins, and were vague at the reality of if the risk is on one or both. Feel quite upset by lack of support and just wondered if any other mums Singleton or twin had similar results?
NB: The hcG and Papp a results are for both together.

Sorry for the delay I've just looked, hcg was 3.86 and papp a was 0.45. Doesn't mean much to me but I remember the screening midwife explaining that they like them both to be as close to 1 as possible so my hcg was fairly high (not sure why that was a surprise given it was twins) and papp a was low which no one has ever mentioned since!
