The Clinical Value of Capillary Blood Cartridge-Based Testing in Neonatal Jitteriness: A Re-Evaluation of the Diagnostic Approach

This study is the first to evaluate the clinical utility of systematic capillary blood cartridge-based testing in jittery neonates using a relatively large cohort. Male neonates were disproportionately represented among cases of NJ. Healthy neonates with jitteriness had normal electrolytes, with hypoglycemia as the only concern. A glucometer test may suffice for evaluation, but those who are small for their gestational age or have initial hypoglycemia require a routine follow-up due to a higher risk of NICU admission.
