Evaluation of a Rapid Immunoassay for Molecular Subphenotype Classification in Pediatric Acute Cardiorespiratory Failure

The authors aimed to evaluate the effectiveness of a rapid immunoassay for classifying molecular subphenotypes in critically ill children with acute cardiorespiratory failure and hyperglycemia. They compared the performance of this rapid assay to conventional multiplex platforms and developed a new classifier based on rapid immunoassay data, which successfully predicted subphenotypes and demonstrated significant prognostic implications, including differences in mortality and response to treatment. The study suggests that rapid immunoassay-based classification can facilitate real-time subphenotype identification in clinical settings, potentially guiding targeted therapies.
