To assess intestinal permeability, lactulose and mannitol excretion is recovered in urine. Variations in transit time in the intestine and renal clearance are normalized through the use of a ratio calculation which reflects the proportion of large to small sugars. This ratio is the researched criteria for assessing suspected intestinal permeability. It is important to note that the accuracy of the results is dependent on patient adherence to test preparations and instructions as well as normal renal function.
Why Run this Test?
- Recovered ratio of lactulose to mannitol
- 5 to 7 business days
