Bilirubin

Also known as: Total Bilirubin, Direct & Indirect Bilirubin

Liver & Digestive Health Blood
Patient Friendly Summary

Bilirubin is recycled-cell pigment awaiting disposal by the liver. Many healthy people have mildly raised values their whole life (Gilbert syndrome) — your doctor can tell the difference.

What this test means

Bilirubin is produced when old red blood cells are recycled and is cleared by the liver into bile. High levels turn skin and eyes yellow (jaundice).

Why it is done

It is done for yellowing of eyes or skin, dark urine, newborn jaundice monitoring, and within routine liver panels.

Understanding your value

If your value is high

High bilirubin may suggest liver conditions, bile-flow blockage, or increased red-cell breakdown. A mild isolated rise can be Gilbert syndrome — a harmless inherited trait.

If your value is low

Low values are normal and not significant.

About the normal range

Total bilirubin is commonly below 1.2 mg/dL. The direct/indirect split helps doctors find whether the issue is before, inside, or after the liver.

When to consult a doctor

Seek medical advice promptly for visible jaundice, dark urine, pale stools, or abdominal pain with raised bilirubin.
