Why This Test Is Done

Your doctor may order this test if you have symptoms like abdominal pain, unexplained fatigue, or signs of liver disease. It can also be used to check for conditions like bile duct blockages, liver disorders, or metabolic issues related to bile acid handling.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for a few hours before drawing blood. If urine is involved, you might need to collect a sample over 24 hours. Always follow your healthcare provider’s instructions.

What the Test Involves
