fractional excretion of lactulose to mannitol ratio 
The gold standard for functional measurements of intestinal permeability in humans is the lactulose/ mannitol test, which measures urinary excretion of the two orally administered non-metabolized sugars over a 6 h period. Analysis by high pressure liquid chromatography or liquid chromatography in combination with mass spectrometry is usually performed on urine samples.

Synonyms
