Neonatal Jaundice

A blood test to measure the level of bilirubin in the baby’s blood, called serum bilirubin level (SBR), may be ordered. This is the most accurate way to measure an SBR and involves collecting a small amount of blood from the hand or via a heel prick.

Additional blood tests or urine tests may also be ordered if there is evidence that the baby’s jaundice is caused by an underlying disorder that will need treatment or if the jaundice is still evident 2-3 weeks after birth (Prolonged Jaundice).
