Total Bilirubin
Bilirubin is a yellow pigment from red blood cell breakdown. Total bilirubin measures combined conjugated and unconjugated forms. Elevated levels cause jaundice (yellow skin/eyes) and indicate liver or bile duct issues.

What is the Total Bilirubin Test?
Bilirubin is a yellow pigment produced when red blood cells break down. The liver processes bilirubin and excretes it in bile. High bilirubin causes jaundice — yellowing of skin and eyes. The test measures both direct (conjugated) and indirect (unconjugated) bilirubin, which helps identify whether jaundice is caused by liver disease, bile duct obstruction, or excessive red cell destruction.
Why Should You Take This Test?
Key marker for jaundice. Fractionation (direct/indirect) helps distinguish liver, bile duct, or hemolytic causes.
Who Should Get Tested?
Yellowing of Skin/Eyes
Jaundice is the primary indication.
Newborn Jaundice
Neonatal bilirubin monitoring is critical.
Liver Disease Patients
Bilirubin tracks liver function.
Suspected Bile Duct Obstruction
Gallstones or tumours blocking bile flow.
