That’s why we are excited to introduce our new Counsyl Insights video series, which highlights new research and peer-reviewed publications relevant to clinical genetics and women’s health. In this series, we will strive to communicate key learnings which can be applied in clinical practice. Subscribe to our Youtube channel to get first access to new videos. Video #1: Clinical Consequences of NIPS No-Calls In the first video of the Counsyl Insights series, authors of the recently published paper in Prenatal Diagnosis discuss the key differences between the two most common sequencing methods used for non-invasive prenatal screening (NIPS): whole-genome sequencing (WGS) and the single-nucleotide polymorphism (SNP) method. This study concludes that for patients with low fetal fraction: WGS has higher sensitivity and will detect more aneuploidies WGS leads to fewer no-calls, fewer false negatives, and significantly fewer invasive procedures Watch our video and learn how the choice of NIPS methodology can result in substantial implications for you and your patients.
