Indirect bilirubin of 35.1μmol/L suggests that the patient’s indirect bilirubin is elevated, which is commonly seen in viral hepatitis, hemolytic disease, cholecystitis, gallstones, sepsis, blood group dyscrasia, severe scalded, pernicious anemia, sepsis, and lead poisoning, in addition to being affected by staying up too late, and diet. The normal value of indirect bilirubin is 1.7~10.2μmol/L, which is an indicator of liver function. Diseases such as viral hepatitis, hemolytic disease, cholecystitis, gallstones, sepsis, blood group incompatibility, severe scalded, pernicious anemia, sepsis, lead poisoning and so on lead to the destruction of red blood cells in the blood is too much, and the liver is unable to turn all the indirect bilirubin into direct bilirubin, so the indicator will rise. In addition, indirect bilirubin can also rise due to staying up late, drinking alcohol, and eating greasy food, so patients must fast before checking their liver function and must not stay up late, otherwise the index will be affected. Indirect bilirubin 35.1 μmol/L needs to be analyzed in combination with other indicators, and after diagnosis of the disease, the patient should receive regular diagnosis and treatment, and should be reexamined in a timely manner. If the indirect bilirubin is found to be persistently elevated, immunological tests must be completed to further understand the function of the liver.
