About Neonatal Bilirubin Threshold Calculator

The neonatal bilirubin calculator compares bilirubin levels with management thresholds using age in hours, gestational age, and risk factors. It supports jaundice review in eligible newborns.

Required Inputs

  • Newborn age in hours.
  • Gestational age.
  • Bilirubin level and unit.
  • Neurotoxicity risk factors when present.

References and Limits

Interpretation is based on 2022 AAP guidance for newborns 35 weeks or older. Verify that the patient is within the applicable range.

Significant jaundice, neurologic signs, or values near exchange thresholds require urgent evaluation and specialist management.

Interpret results as a structured aid for reviewing clinical data, not as an automatic answer. If the output does not match the exam, repeat the measurement, review units, and confirm that the age or date used is correct.

For follow-up, compare results with prior measurements and document the reference source used. Important changes, extreme values, or therapeutic decisions should be evaluated with current guidelines and professional judgment.
