Serum bile acid test

Serum bile acid testing is generally an indicator reflecting liver and biliary function, used to evaluate the synthetic, uptake, and secretory functions of hepatocytes, as well as biliary excretory function. The specific analysis is as follows:

Serum bile acid testing is one component of liver function tests, with a normal reference range of 0–10 μmol/L. Elevated serum bile acid levels may indicate liver diseases such as acute or chronic hepatitis, cirrhosis, or disorders of the biliary system. Therefore, clinically, measuring serum bile acids helps assess whether a patient has liver disease and can aid in diagnosing congenital non-hemolytic jaundice, offering significant diagnostic value.

It should be noted that serum bile acid testing is only one indicator of liver function. A comprehensive assessment should also include other markers such as transaminases, bilirubin, albumin, and globulin levels. An elevated serum bile acid level does not necessarily mean abnormal liver function or impaired hepatic activity. Additionally, pregnant women may experience abnormal bile acid metabolism due to pregnancy; however, in most cases, bile acid levels can return to normal through dietary adjustments.

If a patient experiences any discomfort symptoms, it is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
