|IgG Food Antibody Assessment is a food sensitivity test which helps identify those with true IgE-mediated allergies as well as IgG-mediated food sensitivities. This immunological food sensitivity test measures IgG antibody levels to 87 foods, and total IgE. Additional sensitivity tests are also available for regional inhalants, moulds, vegetables, and spices. This antibody food sensitivity test is ideal for patients who may suffer from delayed reactions/sensitivities to specific foods. It may also provide insight on intolerances, or non-immune responses, to certain foods.
Why use the food sensitivity test?
The incidence of food sensitivities has increased dramatically over the years. It is estimated that up to 20% of the population have adverse reactions to foods, NSAID enteropathy, and post-infectious Irritable Bowel Syndrome (IBS).
Increased total antigenic load related to food and environmental sensitivities has been associated with a wide range of medical conditions affecting virtually every part of the body. Mood and behaviour, including hyperactivity disorders in children are profoundly influenced by food allergies.IgG mediated symptoms may include:
- Ear Infections
Classic skin testing for allergies such as skin-scratch testing only measures IgE-mediated reactions.Assessment of relative IgG antibody levels to a multitude of foods using sensitive Enzyme-Linked-Immnosorbent Assay (ELISA) technology identifies those foods against which the patient is producing antibodies. Measuring both relative IgE and IgG antibody levels provides an invaluable starting point for dietary intervention.
IgE Food Antibodies:
Genova Diagnostics' IgE Food Antibodies is a food allergy test which analyses serum levels of IgE antibodies for 19 combined foods, as well as Total IgE. This is an ideal food allergy test for patients who may suffer an immediate reaction (allergy) or non-immune response to specific foods, such as peanuts or shellfish.
The IgE allergic response is the most well-known food allergy reaction. IgE food allergy reactions usually occur immediately after the ingestion of offending foods, such as peanuts or shellfish. The IgE Food Antibody Profile measures levels of antigen-specific IgE to common foods.
IgE-Mediated Food Allergies:
- Immediate symptom onset (within minutes)
- Circulating half-life of 1–2 days
- Permanent allergies
- Stimulates histamine release
