Question
What is the normal range for newborn jaundice levels?
Answer
The standard values for newborn jaundice can vary based on the time of birth. If jaundice occurs within 24 hours after birth and the serum bilirubin level increases by more than 5mg/dL per day or 0.5mg/dL per hour, or if the jaundice persists for an extended period (more than 2 weeks in full-term infants and more than 4 weeks in premature infants) without subsiding, or even deepens after regression, or if jaundice appears within one week to several weeks after birth, these may be signs of pathological jaundice. Newborn jaundice is one of the most common symptoms in infants after birth, primarily caused by abnormal bilirubin metabolism, leading to elevated bilirubin levels in the blood and subsequent yellowing of the skin, mucous membranes, and sclera.
