This content does not have an English version. Depending on the rate at which the bilirubin level rises, a newborn's risk of developing significant hyperbilirubinemia can be classified as low, intermediate, or high (Figure 2).22 With the assumption that the bilirubin level will continue to rise at the same rate, the physician can predict the potential further progression of the rise and calculate the number of days that the infant may be at risk for bilirubin toxicity.
