Gut Health

Intestinal Permeability (Leaky Gut) Check

When the lining of the intestine and gut microbiome are compromised, unwanted substances can cross the barrier into the blood and activate an immune response in a condition known as 'leaky gut' or 'intestinal permeability'.

About this test

Intestinal permeability, often called 'leaky gut,' occurs when the intestinal barrier becomes compromised, allowing substances to pass through that shouldn't. This can trigger inflammation and various health issues.

What we measure

INTESTINAL BARRIER FUNCTION

Assessment of gut barrier integrity and markers of intestinal permeability.

Zonulin
A protein that regulates intestinal tight junctions. Elevated levels indicate increased intestinal permeability.
Secretory IgA
Immune marker that indicates gut immune function and response to pathogens.
Anti-LPS IgA
Immune response to bacterial endotoxins, indicating gut barrier compromise and systemic inflammation.
