Food Intolerance and Allergy Test
Advanced specialty test to assess relative IgE and IgG antibody levels for dietary intervention
Allergy and sensitivity to food have been associated with a wide range of medical conditions that affect virtually every part of the body, including our mood and behavior.
Classical testing for allergies such as skin-scratch test only measures IgE-mediated reactions. Assessment of relative IgG antibody levels identifies the foods against which the patient is producing antibodies. Measuring both relative IgE and IgG antibody levels provides an invaluable starting point for dietary intervention.
Differences between IgE and IgG Allergy Profiles are summarized below:
IgE reactions are food allergies that are usually immediate to severe (within minutes). IgE Food Antibodies is a food allergy test that analyzes serum levels of IgE antibodies for 19 combined foods, as well as Total IgE.
This advanced specialty test is ideal for: Individuals who suspect that a food is responsible for causing symptoms and wants to check for multiple reactions in one single prick, instead of the traditional numerous needle pricks.
IgG responses to foods are more common but instead of rapid onset, reactions occur in hours to days after consumption (4 to 72 hours). The profile measures IgG levels in blood that react to 87 different foods, including corn, milk, eggs, and wheat. A food reaction patient guide is provided with each test result.
This advanced specialty test is ideal for: individuals with recurrent Gastrointestinal symptoms, headaches, joint aches, rashes, or other vague symptoms.
