If total bilirubin 24.9umol/L is physiologically high, it usually does not need to be examined. If it is pathologically high, it needs to be examined, such as blood routine, liver function, liver ultrasound and so on. The normal range of total bilirubin is 3.4~17.1umol/L, and the test result of 24.9umol/L indicates a mild elevation. If the total bilirubin is high due to physiological reasons, such as staying up late and drinking alcohol, it can be normalized after regular work and rest and quitting drinking, and there is no need to do other tests. If self-regulation can not be reduced to normal, need to be alert to pathological high, such as hemolytic jaundice, hepatitis B viral hepatitis, hepatocellular jaundice, cirrhosis, etc., this situation needs to do blood routine, hepatitis B two half, liver function, liver ultrasound and other related tests. If the total bilirubin is high, if self-adjustment fails to improve it, and if the total bilirubin is persistently high, it is recommended to consult a doctor to clarify the cause of the disease and follow the doctor’s prescription for treatment.
