What is the normal range of bilirubin levels at birth?

• A. 2-6 mg/dL
• B. 5-10 mg/dL
• C. 8-14 mg/dL
• D. 15-20 mg/dL

Answer: (C)

At birth, the normal range of bilirubin levels typically falls between 5 to 10 mg/dL in healthy newborns, but levels can rise rapidly during the first few days of life. It's essential to monitor these bilirubin levels carefully, as physiological jaundice is quite common, and levels can peak around the third to fifth day of life. While levels may vary depending on the infant's health, feeding practices, and other factors, it is recognized that bilirubin levels above 10 mg/dL can be indicative of potential complications, such as hyperbilirubinemia, which requires further evaluation and possible intervention.

This context helps in understanding the importance of monitoring bilirubin levels in newborns, and why levels over 10 mg/dL might raise concern. Hence, while a peak level of 8-14 mg/dL might be observed in some situations, these levels should be interpreted with caution, emphasizing the need for appropriate follow-up and clinical assessment in newborn care.
