Total Bile Acid 15 μmol/L is considered high and needs to be guarded against being caused by eating, cirrhosis of the liver, cholelithiasis, and so on. Total bile acid between 0 and 10 μmol/L is normal, so the detection of total bile acid 15 μmol/L exceeds the normal range, belongs to the high, abnormal situation. Generally, changes in total bile acid can reflect the synthesis and uptake function of hepatocytes and biliary excretory function, etc. However, when the patient eats before the examination, it may also cause a transient increase in serum bile acid. In addition to physiological factors, some people with 15 μmol/L total bile acids should be alerted to the fact that they are caused by liver diseases such as acute hepatitis, chronic active hepatitis, cirrhosis, and biliary tract diseases such as cholelithiasis and biliary tract tumors. In some cases of right heart failure and liver stasis, total bile acid 15 μmol/L may also result. It is recommended that patients with total bile acid 15μmol/L undergo further detailed examination in order to clarify the cause of the disease and then follow the doctor’s instructions for treatment to prevent the condition from worsening and to promote the recovery of the body.
