A critical level of jaundice, particularly in newborns, is indicated by specific bilirubin levels and the timing of its onset.
According to the reference provided, jaundice is considered pathologic, and therefore at a critical level, under the following conditions:
- Jaundice appears within the first 24 hours after birth.
- The total serum bilirubin level rises by more than 5 mg per dL (86 mol per L) per day.
- The total serum bilirubin level is higher than 17 mg per dL (290 mol per L).
- The infant exhibits signs and symptoms suggestive of a serious illness.
In summary, a bilirubin level exceeding 17 mg/dL is considered a critical level of jaundice.
