{"product_id":"intestinal-permeability-2011","title":"Intestinal Permeability","description":"\u003cp\u003eChanges in intestinal permeability are associated with many health conditions including autism, autoimmune disorders, food sensitivities and inflammatory bowel disease. This ‘leaky gut’ causes disease because the perturbed intestinal barrier allows toxic molecules to enter the bloodstream and poison the body.  Intestinal permeability can be measured using the lactulose\/mannitol test. Consider this test for the assessment of intestinal permeability and malabsorption.\u003c\/p\u003e\n\u003cp\u003eThe intestinal permeability test which assesses lactulose and mannitol recovery can be used to monitor improvements or deterioration in intestinal permeability as a result of therapy, disease or drug use.  Furthermore, the intestinal permeability test has been used to monitor the compliance and effectiveness of a gluten-free diet in patients with Coeliac disease.\u003c\/p\u003e\n\u003cp\u003eThe test works on the principle that small molecules (i.e. mannitol) are readily absorbed by the intestinal villi, whilst larger molecules such as disaccharides (i.e. lactulose) are not. These water soluble non-metabolised sugar molecules after penetrating the intestinal tract are excreted into the urine.  Under normal circumstances the ratio of lactulose to mannitol in urine is low (i.e lactulose is not absorbed), mannitol is absorbed.  When the structure of the intestinal epithelium is jeopardised (‘leaky gut’ is present), the large sugar molecule can permeate the mucosa and is recovered in the urine.  In this situation the level of lactulose is increased in the urine and therefore the ratio of lactulose to mannitol is high.\u003c\/p\u003e\n\u003cp\u003eIn addition to assessing leaky gut, this test can also help identify malabsorption.  If a low level of mannitol which normally penetrates the intestinal epithelium is observed, it may indicate malabsorption of small molecules and possible atrophy of the intestinal villi.\u003c\/p\u003e\u003ch3\u003eTest details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest code:\u003c\/strong\u003e 2011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Microbiome Health\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit requirements:\u003c\/strong\u003e IP Test Kit - Urine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollection method:\u003c\/strong\u003e CI05.08.01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest method:\u003c\/strong\u003e GCMS (Gas chromatography mass-spectrometry)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurnaround time:\u003c\/strong\u003e 5 Business Days\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat is measured\u003c\/h3\u003e\u003cul class=\"analytes\"\u003e\n\u003cli\u003e\n\u003cspan\u003eLactulose (recovery %)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eLactulose:Mannitol ratio\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eMannitol (recovery %)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e \u003cdiv\u003e\n\n\u003c\/div\u003e\u003ch3\u003eCommon clinical applications\u003c\/h3\u003e\u003cul class=\"common-conditions\"\u003e\u003cli\u003e\n\u003cimg src=\"https:\/\/nutripath.com.au\/wp-content\/uploads\/2023\/10\/Other-Health-Conditions.png\"\u003e\u003cspan\u003eOther Health Conditions\u003c\/span\u003e\u003cul class=\"common-conditions\"\u003e\n\u003cli\u003e\u003cspan\u003eFatigue\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFood allergy and sensitivities\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGut dysbiosis\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInflammatory Bowel Disease – Ulcerative colitis, Crohn’s disease, Coeliac\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIrritable Bowel Syndrome\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\u003c\/ul\u003e \u003cdiv\u003e\n\n\u003c\/div\u003e\u003ch3\u003eResources\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/nutripath.com.au\/wp-content\/uploads\/2013\/12\/2011-INESTINAL-PERMEABILITY.pdf\"\u003ePatient Brochure\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/nutripath.com.au\/wp-content\/uploads\/2013\/07\/2011-Intestinal-Permeability.pdf\"\u003eSample Report\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eThis test should be ordered and interpreted with guidance from a qualified healthcare practitioner.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Test information is general only.
