Serum/plasma concentration of bile acids (total)

What Is Bile Acid Testing For?

Bile acids are produced by the liver and stored in the gallbladder. They play a key role in breaking down fats in your digestive system. When bile acid levels are measured, doctors often look for signs of liver disease, gallbladder issues, or problems with how bile moves through the digestive tract. High or low levels may indicate conditions like cirrhosis, bile duct blockages, or certain metabolic disorders.

Why Might Your Doctor Order This Test?

Your doctor may recommend a total bile acids test if you have symptoms like unexplained fatigue, jaundice (yellowing of skin/eyes), abdominal pain, or if they suspect liver disease, bile duct issues, or other gastrointestinal problems. It can also be part of a broader evaluation for conditions like primary biliary cholangitis or other metabolic liver disorders.

How Is the Test Performed?

A blood sample is drawn from a vein, usually in your arm. The sample is then sent to a lab for analysis. No special preparation is typically needed, but you may be asked to fast for a few hours before the test if instructed by your healthcare provider.

What Are Common Results and Their Meanings?

Results are compared to a reference range specific to your lab. Elevated levels may suggest liver disease, bile duct obstruction, or certain metabolic disorders. Lower levels might indicate conditions like cholestasis (blocked bile flow) or other liver-related issues. Your doctor will interpret the results in the context of your symptoms and medical history.
