|Key Information||Appropriate Tests|
Bilirubin (total and direct) to document unconjugated hyper-bilirubinaemia; ALP, ALT, AST, GGT to exclude liver disease; FBC with blood film to exclude haemolysis.
If the diagnosis is uncertain the serum bilirubin fasting level can be measured and should exceed the non-fasting level by > 50%.
This test should not be done during intercurrent illness.
Liver biopsy is not required to establish the diagnosis.
