One size does not fit all: interpreting laboratory data in pediatric patients

Area of Science:

• Pediatric Nephrology
• Clinical Laboratory Science
• Biomedical Informatics

Background:

• Laboratory test results for kidney stone risk factors are typically reported using adult reference ranges.
• These adult ranges are not directly interpretable for pediatric patients, posing challenges in diagnosis and management.
• Accurate interpretation of pediatric lab values is crucial for identifying kidney stone risk in children.

Purpose of the Study:

• To develop and present a computational solution for converting adult laboratory reference ranges to pediatric-adjusted relative units.
• To enable age-specific comparison of laboratory results for pediatric patients.
• To facilitate the flagging of out-of-range values in pediatric kidney stone risk assessments.

Main Methods:

• Development of a conversion algorithm to adjust laboratory output for pediatric patients.
• Implementation of age-specific reference ranges for comparison.
• Creation of a system to flag abnormal pediatric laboratory values.

Main Results:

• The developed solution successfully converts laboratory results into pediatric-adjusted relative units.
• The system accurately compares pediatric results against age-specific reference ranges.
• Out-of-range values indicative of kidney stone risk factors are effectively flagged.

Conclusions:

• Clinicians can leverage existing computer resources to create practical solutions for clinical practice challenges.
• The presented method offers a viable approach to improve the interpretation of laboratory tests for pediatric kidney stone risk.
• This solution enhances the ability to identify and manage kidney stone risk in the pediatric population.
