The intestinal permeability test measures the permeability of the intestine using eleven types of PEG molecules of different sizes. The molecules are resistant to degradation and will end up in the urine intact, depending on the ease with which they can pass the intestinal wall. The molecules of different sizes are measured in the urine. An absorption profile can be assembled based on this measurement. It can also identify other problems, such as malabsorption. In this case, small molecules will also be greatly reduced in the urine.
The test is recommended for patients with intestinal complaints such as: ulcerative colitis, Crohn’s disease, spastic intestine, Celiac Disease, migraine and eczema.
