What Level of Jaundice is OK?
There is no single "OK" level of jaundice. The acceptable level of bilirubin (the pigment causing jaundice) depends heavily on the individual's age and overall health. In healthy adults, a total bilirubin level of less than 1 mg/dL is considered normal.[1, 6] However, newborns have different bilirubin levels.
Newborns have a higher rate of bilirubin production than adults (6-8 mg/kg/day vs. adult rates).[2] This leads to physiological jaundice, which is common in the first few days of life and often resolves without treatment.[5, 7, 10] In newborns, bilirubin levels can reach up to 18 mg/dL by 3-4 days of age (7 days in Asian infants) and still be considered within the normal range for the developmental stage.[10] However, levels exceeding 25 mg/dL can be dangerous and require immediate medical attention due to the risk of kernicterus (brain damage).[8]
Key Points:
- Normal adult bilirubin: Less than 1 mg/dL[1,6]
- Newborn bilirubin: Varies significantly; elevated levels are common in the first few days of life.[5, 7, 10]
- High-risk bilirubin levels: Levels exceeding 25 mg/dL require immediate medical intervention.[8]
It is crucial to consult a healthcare professional to assess jaundice and determine the appropriate course of action. They will monitor bilirubin levels and determine if intervention is necessary. Self-treating jaundice can be harmful.
