Description
Why It’s Done:
A bilirubin test is commonly ordered to:
• Evaluate liver function
• Diagnose jaundice (yellowing of the skin and eyes)
• Detect liver diseases, such as:
o Hepatitis
o Cirrhosis
o Liver damage
• Investigate causes of hemolytic anemia, where red blood cells break down rapidly
• Monitor newborns for neonatal jaundice
• Assess bile duct obstruction or gallbladder issues
Abnormal levels may indicate:
• High Indirect Bilirubin: Hemolytic anemia, Gilbert’s syndrome
• High Direct Bilirubin: Liver disease, bile duct obstruction, hepatitis
Preparation:
• Fasting may be required: Your doctor may ask you to avoid eating or drinking (except water) for 4–6 hours before the test.
• Avoid alcohol before the test, as it can affect liver function results.
• Inform your doctor about any medications or supplements you’re taking, as some (like antibiotics, birth control pills, or certain anti-inflammatory drugs) may impact bilirubin levels.
• A blood sample is taken from a vein in your arm for analysis
