Asset Details

  • Description:
  • Results of a hydrogen breath test of an individual with lactose intolerance with simultaneous assessment symptoms and H2 levels, indicating lactose fermentation by the microbiota. An H2 increase by ≥20 ppm over baseline indicates lactose malabsorption. When 13C-labelled lactose is administered, 13CO2 levels indicate absorption and metabolisation of 13C-labelled lactose by the subject. Patient reports of abdominal symptoms subsequent to increases in these markers is diagnostic of lactose intolerance.
