This simple home test analyzes urine for the clearance of two non-metabolized sugars, lactulose and mannitol. It identifies 'leaky gut' and malabsorption.

The Intestinal Permeability Assessment is a powerful and noninvasive assessment of small intestinal absorption and barrier function in the bowel. The small intestine uniquely functions as a digestive/absorptive organ for nutrients, as well as a powerful immune and mechanical barrier against excessive absorption of bacteria, food antigens, and other macromolecules. Both malabsorption and increased intestinal permeability(i.e.leaky gut) are associated with chronic gastrointestinal imbalances, as well as many systemic disorders.

Increased permeability of the small intestine can:

  • Increase the number of foreign compounds entering the bloodstream.

  • Allow bacterial antigens capable of cross-reacting with host tissue to enter the bloodstream, leading to auto-immune processes.

  • Enhance the uptake of toxic compounds that can overwhelm the hepatic detoxification system and lead to an overly sensitized immune system.

Increased gut permeability has been observed in a range of disorders such as:

  • Inflammatory Bowel Disease (IBD)

  • Food allergy

  • Inflammatory joint disease

  • Chronic dermatologic conditions

Studies have demonstrated that the increased permeability observed in patients with ankylosing spondylitis, rheumatoid arthritis, and vasculitis may be an important factor in thepathogenesis of these disorders. Decreased permeability, on the other hand, appears as a fundamental cause of malabsorption, subsequent malnutrition, and failure to thrive.

In certain disease states of the small intestine, such as gluten-sensitive enteropathy, permeability to large molecules may increase, while permeability to small molecules decreases, a result of damage to the microvilli. As a result, nutrients become even less available to assist in the detoxification of antigens flooding the system.

Possible causes of intestinal permeability include:

  • Intestinal infection

  • Ingestion of allergenic foods or toxic chemicals

  • Deficient secretory IgA

  • Trauma and endotoxemia

  • NSAIDs

Testing Procedure:
The Intestinal Permeability Assessment directly measures the ability of two non-metabolized sugar molecules to permeate the intestinal mucosa. The patient drinks a premeasured amount of lactulose and mannitol. The degree of intestinal permeability or malabsorption is reflected in the levels of the two sugars recovered in a urine sample collected over the next 6 hours.

Analytes:
A measurement of urinary clearance of the challenge substances lactulose and mannitol, and lactulose/mannitol ratio.

Specimen Requirements:
15cc urine (before drink), 15ccaliquot of 6-hour urine (after drink)

Before Patient Takes this Test:

  • Make sure fasting glucose level is not high

  • Inform practitioner about medication use

  • Do not eat or drink anything for 8 hours
