- Reviewed 701 high-risk pregnancies with both GW-NIPT and prenatal microarray.
- For aneuploidies, CNVs ≥7Mb, and select microdeletions, sensitivity was 93.8%, specificity was 97.3%, and PPV was 63.8%.
- “Conclusions: While microarray provides the most robust assessment of fetal CNVs, this study suggests that genome wide cfDNA can reliably screen for large CNVs in a high-risk cohort. Informed consent and adequate pretest counseling are essential to ensuring patients understand the benefits and limitations of all prenatal testing and screening options.”
