I know it's nowhere near high risk, but last time I had 1:9000 so it seems a lot higher to me! I also know it's no guarantee of having a non-Downs baby, just a risk factor. I'm over 35 now, and from what I could read, a normal blood serum multiplies the age risk by 4, which this is over, so bloods must have been normal and NT smallish (1.3). Is 1:1600 less of a risk at 35 (because it's mostly composed of maternal age risk) than it would be at a younger age where NT/blood would have shown markers to give that sort of number?

Is 1:1600 low enough as a Downs risk, or would you have Harmony as well?
