The normal value of total bilirubin is 3.4~17.1 μmol/L. 74 μmol/L indicates elevated bilirubin, which is commonly seen clinically in hemolytic disease, liver disease, gallbladder disease, etc.
1. Hemolytic disease: When red blood cells are destroyed, bilirubin in red blood cells is released, which will lead to mild elevation of blood bilirubin.
2. Liver disease: When liver function is impaired and hepatocytes are ruptured, the liver is unable to convert direct bilirubin into indirect bilirubin, resulting in a large amount of direct bilirubin aggregation and an elevated total bilirubin.
3. Gallbladder disease: When bilirubin cannot be excreted smoothly due to cholecystitis or biliary obstruction, a large amount of bilirubin accumulates and total bilirubin can be elevated.
In addition, total bilirubin of 74 umol/L may also be related to other causes, it is recommended to go to the hospital in time, improve the examination, under the guidance of professional physicians to clarify the cause of the disease, and give targeted treatment or therapy.
