i'm wondering whether your risk was the 1:161 or whether that's the general risk for your age? when i got my results they also told me two figures - one was our actual results & the second was what the risk is typically of someone my age. because i'm in my 30's the risk for my age is usually quite high but the risk of this PG was far lower - using the combined blood test & scan results.

sorry if i've misinterpreted this, but just wondering if maybe that's why you have the two figures?
