Hi i feel you! The NT for my baby was thick and my risk came back as 1:10 for DS. Because it was so high risk, i was advised to go for CVS or amnio instead of nipt. CVS/Amnio is a diagnostic test and hence can pinpoint not only DS but other chromosomes. I went for amnio in the end and the result came back all normal. So the oscar test was a false positive. Oscar test tend to give older women higher risk, so you may consider going for CVS/amnio (do note these 2 are invasive tests hence there is a slight risk of miscarriage of around 1:300). You may discuss with your gynae or husband.
