Description
Why It’s Done:
The Total Bilirubin test is commonly performed to:
• Evaluate liver function
• Diagnose jaundice, especially in newborns and adults
• Identify liver diseases, such as hepatitis or cirrhosis
• Detect bile duct obstruction
• Monitor conditions that cause increased breakdown of red blood cells (hemolytic anemia)
High total bilirubin levels may indicate:
• Liver or bile duct problems
• Increased destruction of red blood cells
• Issues with bilirubin processing in the liver
Preparation:
• Fasting may be recommended: Your doctor might ask you to avoid food and drink (except water) for 4–6 hours before the test.
• Avoid alcohol before the test, as it can affect liver function.
• Inform your doctor about any medications or supplements you are taking, as some can interfere with bilirubin levels.
• The test involves a simple blood draw from a vein in your arm
