ALL visibly jaundiced neonates need a bilirubin measurement.
Assessment of jaundice must always include assessment of health, risk factors and signs of system illness.
Unwell jaundiced baby of any age:
Immediate telephone referral to Neonatal (if less than 1 week old) or Acute Paediatric inpatient service, or 999 if A, B, or C compromise.
Apparently well baby with jaundice:
