Unfortunately, the provided reference does not explicitly state a "normal bilirubin rate of rise." Instead, it gives information about typical peak bilirubin levels in newborns. The reference mentions that:
- The average total serum bilirubin level usually peaks at 5 to 6 mg per dL (86 to 103 μ mol per L) on the third to fourth day of life.
- Bilirubin elevations of up to 12 mg per dL are sometimes seen.
Without a specific rate, we can infer some things, but a true "normal rate of rise" isn't defined.
To better understand bilirubin and its levels in newborns, it is important to consider the following:
- Peak Levels: The reference provides peak bilirubin levels that are typically reached within the first few days of life.
- Normal Range: While not a rate, knowing that bilirubin can elevate up to 12 mg/dL is important, but any concerning rise or level would warrant medical evaluation.
- Conjugated vs. Unconjugated Bilirubin: The reference also mentions that bilirubin elevations should primarily be the unconjugated form.
Therefore, based on the provided reference, it is not possible to definitively state a normal bilirubin rate of rise. The reference focuses on the peak levels observed in newborns.
