This comparative illustration clearly shows the difference between a healthy newborn and one affected by severe jaundice, with yellow-tinted skin and sclera (whites of the eyes). The image highlights one of the most visible signs used in the diagnosis of jaundice in newborns. Clinicians also use tools such as a transcutaneous bilirubin meter and blood tests to measure serum bilirubin levels. Early identification is essential to prevent complications like kernicterus. This visual serves as a helpful reference for both healthcare professionals and new parents in recognising the severity of jaundice.
