Hi, I'm currently 10 weeks pregnant and my gynae has sent me to do an OSCAR test 2 weeks later and subsequently a NIPT test at 14 weeks (due to vanishing twin, I'm doing the NIPT test later). I have read that the OSCAR test often give false positives, in that case, why gynae even bother to still do OSCAR test?
By the way I'm 38 so kinda high risk and worried now.
