I did a colonscopy and the large intestine is fine but the doctor went further into my lower end opening of my smailll intestine and found five small inflammations so he took biopsies..Would this test help and what way is better as th labs have different ways

Hi there!

Intestinal absorption (?permeability) cannot be described by urine tests, though it can be affected by both lactulose and mannitol.
Hope this information is helpful.

Take care!
