Testing for Leaky Gut
There are two ways to medically test leaky gut and, more importantly, some of its effects.
standard leaky gut Lab test is called the Lactulose/Mannitol Challenge.
You drink a solution containing two substances (non-metabolised sugar
molecules lactulose and mannitol) and then collect your urine. Lactulose
is large and penetrates poorly through the intestinal barrier so an
elevated level of lactulose in your urine is indicative of increased
intestinal permeability. Mannitol, on the other hand, is usually well
absorbed so a low percentage recovery of mannitol is indicative of
malabsorption. A high lactulose/mannitol ratio means that you have
increased gut permeability.
- Another test, perhaps more valuable,
is to measure the effects of leaky gut with a food allergy test,
specifically IgE, IgG4 and IgA antibodies. There is scientific certainty
that leaky gut will cause food sensitivities. If leaky gut is to be
healed, those foods must be identified and removed.
Allergic and other hypersensitivity reactions to foods and aeroallergens are characterized by elevated allergen-specific antibody levels in the affected individual’s blood. Research indicates that these types of reactions are implicated in a number of health problems. There are MANY - several dozen - reactions ranging from an immune based food allergy.
