  • This publication describes results from a nationwide implementation study in the Netherlands that examined the use of NIPT as a first-tier test offered to all pregnant women, with the option to have findings beyond trisomies 21, 18, and 13 reported based on patient request. 78% of pregnant women chose to have these additional findings reported to them.

  • This publication examined the clinical performance of Expanded NIPT for both aneuploidy and genome-wide microdeletion/microduplication syndromes in an all-risk pregnancy population. A cohort of 94,085 patients with singleton pregnancies were prospectively enrolled. This Expanded NIPT detected a clinically significant fetal chromosome abnormality in 1.2% of samples and calculated the respective PPVs for the screen positive abnormalities.
