A Total Bilirubin test measures the amount of bilirubin in your blood. Bilirubin is a yellowish pigment produced when red blood cells break down. The liver processes bilirubin so it can be excreted from the body.
What This Test Measures
Total Bilirubin:
The combined amount of unconjugated (indirect) and conjugated (direct) bilirubin. Elevated total bilirubin can cause jaundice (yellowing of skin and eyes).
Reference Range
Normal: 0.1-1.2 mg/dL
Who Should Consider This Test
• Yellowing of skin or eyes (jaundice)
• Evaluating liver function
• Investigating causes of dark urine or pale stools
• Monitoring liver disease
• Newborn jaundice screening
• Part of comprehensive liver evaluation
What Causes Elevated Bilirubin

• Hemolytic anemia (red blood cells breaking down too fast)

• Hepatitis
• Cirrhosis
• Alcoholic liver disease

• Gilbert’s syndrome (benign genetic condition)
