Genetic Testing Protocols for Critically Ill Infants

This guide outlines the genetic testing protocols employed by two hospitals for critically ill infants in the NICU. Hospital A utilizes rapid genome sequencing for babies whose symptoms cannot be fully explained by other medical conditions, while Hospital B follows a case-by-case approach, requiring a genetics consult before ordering such tests. The case study of an infant named Luca illustrates the impact of these protocols on patient outcomes. Luca was admitted to the NICU with respiratory distress and other concerning symptoms. Hospital A's protocol allowed for rapid genome sequencing, leading to a diagnosis of Kabuki syndrome within days, which informed his prognosis and guided further evaluations and interventions. The guide emphasizes the importance of timely genetic testing in improving outcomes for infants with underlying genetic conditions, highlighting how early diagnosis can facilitate necessary referrals and support for families.
