Analysis index

1 ml serum

Normal:

Empty-stomached: < 10 µmol/l

2 hours after meal: < 20 µmol/l

Biliary obstruction:

Empty-stomached: > 180 µmol/l

2 hours after meal: > 180 µmol/l

Significantly increased, no difference between fasting levels and postprandial levels

Intrahepatic cholestasis:

Empty-stomached: approx. 100 µmol/l

2 hours after meal: approx. 120 µmol/l

Lower than in extrahepatic causes

Portosystemic shunt:

Empty-stomached: < 10 µmol/l

2 hours after meal: > 180 µmol/l

Impaired intestinal motility or gall bladder contraction:

Empty-stomached: 25 µmol/l – 50 µmol/l

2 hours after meal: < 20 µmol/l

Fasting levels are higher than postprandial levels

Intestinal malabsorption:

Empty-stomached: approx. 10 µmol/l

2 hours after meal: approx. 10 µmol/l

Hepatobiliary dysfunction, pruritus during pregnancy, decreased circulation of the enterohepatic system

Evaluation should preferably be carried out postprandially
