The soft markers are typically obtained at the time of the second trimester anatomy scan. It is going to be a long two weeks waitingfor the full panel to come back though. Universal NIPT adoption is not yet cost-effective.31 The Society for Maternal-Fetal Medicine designates some high-risk women as ideal candidates for NIPT screening (risk factors include maternal age of 35 years or older at the time of delivery; ultrasound findings indicating higher risk of aneuploidy; a previous pregnancy affected by trisomy 13, 18, or 21; or positive results from first- or second-trimester serum screenings).32 Positive NIPT results should be confirmed with invasive diagnostic testing, particularly if pregnancy termination is being considered. first-trimester screen, integrated screen, sequential screen, contingent I had the NIPT @ 12 weeks and everything came back as normal 99% negative for Down Syndrome.
