Pathogen-Associated Immune Reactivity Screen (Cyrex Laboratories)

Giardia lamblia

Optimal Result: 0.2 - 1.6 ELISA Index.

G. lamblia is a flagellated protozoan parasite that colonizes and reproduces in the small intestine. G. lamblia causes giardiasis. Giardiasis does not spread via the bloodstream, nor does it spread to other parts of the gastrointestinal tract. Giardiasis remains in the lumen of the small intestine. Chronic infection with Giardia may abate and the patient could become asymptomatic. Asymptomatic individuals may become reservoirs for spreading the infection. Antibodies against G. lamblia may cross-react with human tissue antigens such as tubulin, actin, actinin, tropomyosin and others. The end result may be autoimmunity against those tissues.

What does it mean if your Giardia lamblia result is too high?

Increased risk of gastrointestinal disorders including intestinal permeability and autoimmunity against gastrointestinal tract tissues.
