OSCAR, NIPT or both?
Which test(s) are you considering? Is it also possible to do just the NT scan (part of OSCAR) + NIPT? Read it somewhere but my gynae recommends just the OSCAR for me as I am still young and the odds are low.
When I was 29 yo, my gynae only asked me to do Oscar. When I was 33, she asked me to do nipt. So I just followed her advice. I just did nipt at 37 but she also did the NT scan for me to check the thickness of the neck and nasal bone/
