Two-Fold Increase in Diagnosis and Change of Management

Finding the right diagnosis for a patient with a rare genetic disease can lead to improved clinical management. WGS has shown to have a higher diagnostic efficacy, changing clinical management for NICU patients by two-fold compared to standard testing.3 Introducing WGS in the NICU changes the strategy for the most vulnerable babies affected by suspected genetic disease.

Faster Answers with WGS

Compared to standard genetic testing, WGS has a higher diagnostic yield (3%-20% vs 31%-57%, respectively)* and can provide critically-ill infants an increased likelihood of receiving a diagnosis.3-7 Offering WGS as a first-tier test early in the NICU admission when the underlying etiology is unclear can lead to a shorter time to diagnosis and inform care faster.

A Timely Diagnosis May Help Avoid Unnecessary Tests or Procedures & Reduce Length of Stay

Undiagnosed NICU patients with genetic disorders have shown to have higher resource utilization and longer hospital stays. Families may undergo financial hardship while hospitals absorb additional costs due to limited reimbursement.

However, enabling early intervention and improved clinical outcomes with WGS may facilitate patient workups and minimize medical costs by potentially reducing the length of stay and the need for other tests or procedures.
