Individuals with neurological, gastrointestinal, and movement disorders often suffer from IgG food allergies. These patients may continue to eat offending foods unaware of their potential effects. IgG antibodies provide long term resistance to infections and have a much longer half life than the traditional IgE allergy. Symptoms may occur hours or days after the offending food has been eaten. The 93 foods tested in the IgG Food Allergy Test plus Candida can identify problem food so it can be eliminated from the patient’s diet. Samples are referred to Great Plains Laboratory for analysis.
