Total bilirubin of 36umol/L, i.e. elevated total bilirubin, is generally not considered serious if it is due to liver injury caused by physiological reasons such as improper dietary and living habits, which leads to elevated total bilirubin. If the total bilirubin is elevated due to viral hepatitis, intrahepatic bile duct stones, hemolytic anemia, etc., the condition is more serious and requires treatment. The normal value of total bilirubin in serum is 1.7 to 17.1 umol/L, and jaundice can be seen clinically when it exceeds 34.2 umol/L. So a total bilirubin of 36umol/L may present with generalized yellowing of the skin and sclera and itching of the skin. There are the following reasons for elevated total bilirubin. 1. Physiological reasons: if there are long-term late night, drinking, exertion, etc., it will cause liver damage and lead to elevated total bilirubin, after removing the above triggers, the total bilirubin value can be returned to normal, so it is generally not considered serious. 2. Pathological causes: If you suffer from acute cholecystitis, common bile duct stones, hemolytic anemia and other causes of elevated total bilirubin, you need to be treated in time. It is recommended to quit drinking and maintain a healthy lifestyle, and if you find elevated total bilirubin, you should consult a doctor for a clear diagnosis in order to avoid delaying your condition.
