What is the normal bilirubin range for neonates in umol/L?

The normal bilirubin range for neonates is well-established in clinical practice, as it is an important measure of liver function and can indicate underlying health issues, such as jaundice. The correct range of 1.7-180 µmol/L aligns with the clinical understanding that bilirubin levels can vary in neonates but generally fall within this range due to their immature hepatic systems.

During the first week of life, it's common for bilirubin levels to rise as the newborn's liver begins to process bilirubin more effectively. Levels that exceed the normal range can lead to jaundice, which may require monitoring and potentially treatment. Understanding this bilirubin range is crucial for healthcare professionals to assess the neonate's health and intervene when necessary.

The other ranges presented do not accurately reflect the expected bilirubin levels for neonates based on clinical guidelines and studies. Recognition of these levels helps ensure that any deviations from the norm can be investigated and treated promptly.
