What we test

Lactose Malabsorption

Hydrogen/methane breath tests are highly specific and sensitive tools for the diagnosis of FODMAP malabsorption. They are considered first line interventions in the diagnostic workup of IBS symptoms and are recommended before dietary intervention. Breath tests avoid unnecessary food restrictions and adverse effects on gut microflora.

This breath test looks for lactose malabsorption which is advised in all IBS sufferers, especially those with symptoms related to milk/dairy products.

This represents the amount of hydrogen present in an exhaled breath a period of time after taking a lactose dose. Hydrogen is produced by microbial fermentation of carbohydrates in the gut.

Breath hydrogen is used for measurement of malabsorption where possible. If breath hydrogen production is low, further tests are conducted using equipment that also measures methane (CH4).
