Verification of Risk Assignment for Whole Chromosome Using SNP-based NIPT in Vanishing Twin Pregnancies (VANISH)
The purpose of this study is to collect blood samples from women carrying a vanishing twin pregnancy to further develop Natera's non-invasive prenatal screening test to provide information about possible chromosomal conditions for the living twin
Inclusion: Women with either ultrasound-documented dizygotic (DZ) twin pregnancy or those whose Panorama Test™ results suggest increased risk for vanishing twin.
Exclusion: Maternal history of bone marrow or organ transplantation; Monozygotic twin pregnancy; Non twin pregnancy.
