Ok, I cannot tell if I'm dumb or if my head is just spinning so much from all this I can't make sense of it!
I have my Iona report that's given me high tosh but I can't understand how when I read the report. 😟
Does anyone understand these that can help me understand?

So if it's like mine, it'll look like this.....

As far as I was told, the background risk is the equivalent of what the NHS gave me. In my case, it was 1:14 for Down syndrome and 1:28 for Edwards and Pattau Syndrome. So a big difference. The middle column is the likelihood ratio of risk from the fetal DNA sample taken from your blood and the adjusted age probability is relating to your age where they have adjusted the result according to the risk affected by age. I think that's right, that's how it was explained to me. I hope that helps OP.
