Background and ObjectivesCurrent potassium reference intervals for neonates fail to account for sampling method differences and prematurity-related factors, leading to unnecessary resampling and interventions. We aimed to establish sampling-specific potassium reference intervals for term and preterm neonates using comprehensive electronic health record data. MethodsWe analyzed 195 606 blood gas measurements from 10 290 neonates (2007-2024) at a tertiary neonatal intensive care unit. After ex-cl...
