Normal range of jaundice index

The jaundice index is mainly used to assess whether a person has jaundice and the severity of jaundice. Generally speaking, the normal range of the jaundice index varies depending on the detection method and different populations.

Total bilirubin is one of the important indicators for measuring the jaundice index. The normal range of total bilirubin in adults is usually 3.4-17.1μmol/L. For newborns, due to their physiological characteristics, the jaundice index will have a process of change. Within 24 hours after birth, the neonatal jaundice index generally does not exceed 6mg/dL; within 48 hours after birth, the jaundice index usually does not exceed 9mg/dL; 72 hours after birth and thereafter, the jaundice index generally does not exceed 12.9mg/dL. The jaundice index outside the normal range may be caused by a variety of reasons. For example, liver diseases such as hepatitis and cirrhosis can affect the metabolism and excretion of bilirubin, leading to an increase in the jaundice index; bile duct obstruction, such as gallstones and bile duct cancer, can also prevent bilirubin from being excreted normally, causing jaundice; hemolytic diseases can increase the destruction of red blood cells and excessive bilirubin production, leading to jaundice.

Knowing the normal range of jaundice index is important for timely detection and diagnosis of diseases. If jaundice symptoms or abnormal jaundice index occur, you should seek medical attention as soon as possible for early diagnosis and treatment.
