Total Bilirubin blood test
Normal Reference Range
0 – 7 Days = <100U/L
>7 Days = 0 – 17U/L
Test Information
A by-product of the breakdown of haemoglobin, bilirubin is correlated with the level of hepatic function and red cell turnover in the blood. Hepatic cholestasis (caused by gallstones) and liver cirrhosis are both associated with elevated bilirubin levels, as are hepatitis, several autoimmune diseases, Crigler-Najjar syndrome, and Gilbert’s syndrome.
Clinical Indications
Diagnosis of haemolytic anaemia and diagnosis and monitoring of hepatic impairment or secondary to other causes (e.g. pancreatitis).
