Bilirubin, Total (Serum or Plasma)

Why This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms like jaundice (yellowing of skin or eyes), dark urine, pale stools, or unexplained fatigue. It’s also used to monitor liver function, detect bile duct blockages, or check for conditions like hemolytic anemia or liver disease.

What to Expect Before the Test

You won’t need special preparation. For blood tests, a small needle will draw blood from a vein in your arm. If you’re nervous, let your healthcare provider know so they can help you relax.

What the Results Mean

Higher-than-normal bilirubin levels may indicate problems with red blood cell breakdown, liver function, or bile flow. Lower levels are usually normal but can sometimes signal liver issues in rare cases. Always discuss your results with your doctor.

Common Conditions Linked to Bilirubin Levels

Elevated bilirubin is often seen in conditions like jaundice (from liver or bile duct issues), hemolytic anemia (rapid red blood cell destruction), or liver diseases (like hepatitis or cirrhosis). Low levels are less common but may sometimes appear in liver disorders or certain genetic conditions.
