Urine Bile Pigment

Specimen Required

Urine (Random/Spot)

Fasting Required

Purpose of the Test

Urine bile pigment testing may be done to determine if there are any problems with the liver or bile ducts that can cause excess bilirubin to accumulate in the body. It is used to diagnose conditions such as jaundice, hemolytic anemia, liver disease, and biliary tract disorders.

When this test is required

This test may be requested when you have symptoms of liver or bile duct disorders, such as jaundice, dark urine, pale stools, and abdominal pain. It may also be ordered as part of a routine liver function test panel.

What the Test Detects

The urine bile pigment test measures the levels of bilirubin in a urine sample. Bilirubin is a yellow pigment that is formed when red blood cells are broken down in the body. The liver helps to process bilirubin and excrete it in bile, which is then eliminated from the body in stool. If the liver is not functioning properly or if there is an obstruction in the bile ducts, bilirubin may accumulate in the body and be excreted in the urine.

Preparation for the Test

No specific preparation is needed for this test. However, your healthcare provider may advise you to avoid certain medications or supplements that could interfere with the test results.

Sample Requirements

A random urine sample is typically collected for this test.

Additional Notes

This test is often performed in conjunction with other liver function tests, such as serum bilirubin, alkaline phosphatase, and liver enzyme tests, to help diagnose liver and bile duct disorders. It is important to follow your healthcare provider’s instructions for preparation and testing to ensure accurate results.
