Indications for IgG 115

Indications for Gliadin

Overview

This test combines a 115 food IgG antibodies test and an anti-gliadin antibody test, to detect food allergies and gluten sensitivity, respectively.

Overview for IgG 115

The majority of adverse immune reactions to foods classified as type II, III, or IV with delayed system onset, are mediated by IgG and are termed food sensitivities. It has been estimated that 90% of immune reactions to foods are non-IgE or delayed symptom onset food allergies. A single blood test can identify patient’s food sensitivities. Recommended treatments for food sensitivities is elimination of reactive foods from the diet for a period of 3 to 4 months followed by reintroduction and rotation. This test, tests for 115 foods.

Overview for Gliadin

Over 100 chronic conditions, including celiac disease, have been associated with increased levels of Anti-Gliadin antibody (gliadin is the protein component of gluten). Since the 1970’s, gluten-free diets have shown to be a reliable treatment in allowing celiac patients to return to “normalcy”.

Recent research has shown the detection of Anti-Gliadin IgG and IgA to be an indicator of gliadin involvement in the medical condition. The test detects both IgG and IgA to gliadin by the ELISA method. This test is a very effective screening test for gliadin and is a good method for monitoring patients’ adherence to a gluten-free diet.
