What Is Bile Acid Testing For?

Your healthcare provider may order this test to evaluate liver function, identify bile duct blockages, or assess conditions like gallstones, liver disease, or bile acid malabsorption. It can also help diagnose certain metabolic disorders.

How Is This Test Performed?

A blood sample is taken from a vein, usually in your arm. The blood is then sent to a lab for analysis using a specialized method to measure bile acid levels.

What Are Common Conditions Monitored?

This test is often used to monitor conditions such as cholestasis (blocked bile flow), liver cirrhosis, primary biliary cholangitis, or after liver or gallbladder surgery.

What Do Results Mean?

Results may be compared to a reference range provided by your lab. Elevated levels could suggest bile duct obstruction or liver disease, while lower levels might indicate malabsorption or other metabolic issues.

Clinical interpretation
