Total bilirubin 27 is slightly above normal, not too high. The causes of elevated total bilirubin may include physiological factors, liver diseases, hemolytic diseases, biliary tract diseases and so on. 1. Physiological factors: If you stay up late for a long time, or drink a lot of alcohol the day before the examination, it may also lead to high total bilirubin. 2. Liver diseases: Acute hepatitis, chronic hepatitis, cirrhosis, liver cancer or bile duct cell carcinoma in the liver can cause an increase in total bilirubin. 3. Hemolytic disease: Hemolysis may be caused by infection, autoimmune disease and other factors, resulting in high total bilirubin. 4. Biliary tract diseases: common diseases such as cholecystitis, cholangitis, choledocholithiasis, choledocholithiasis, choledocholithiasis, choledocholithiasis tumors and so on, which will lead to extra-hepatic biliary stasis and cause high total bilirubin. If the total bilirubin is 27, it is recommended to go to the hospital as soon as possible for examination and early treatment after the cause is clarified.
