Allergix® IgG4 Food Antibodies 90 - Serum

The Allergix® IgG4 Food Antibodies 90 is a food sensitivity test which helps identify those with IgG–mediated food intolerances. IgG4 antibody is related to delayed or non–atopic food reactions that exacerbate or contribute to many different health problems. This antibody food sensitivity test is ideal for patients who may suffer from delayed reactions/sensitivities to specific foods.

What is an IgG4 food sensitivity response?

An IgG4 response to food is actually more common than the IgE response, which causes an immediate reaction. These food sensitivity reactions are more difficult to notice since they can occur hours or even days after consumption of an offending food. In some cases, a person's reaction to a food may occur several days after eating the offending food and the link between the food and their symptoms may not be connected. These hidden food “allergies” are actually food “sensitivities” and are caused by increasing blood levels of IgG4 antibodies in reaction to specific foods. This profile measures the IgG4 levels in serum that react to 90 different foods, including commonly eaten foods such as corn, milk, egg, and wheat. A food intolerance reaction patient guide is provided with each test result.

IgG–Mediated symptoms may include:

  • Asthma
  • Arthritis
  • Migraines
  • Ear Infections
  • Eczema
  • Sinusitis
  • Urticaria
  • Colitis

Why use the food intolerance 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).

Genova Diagnostics Innovation in IgG Antibody Food Intolerance Testing:

  • New patent–pending IgG4 assay allows our test to show less false positives leading to better patient compliance
  • First test to quantitate IgG4
  • Eliminates non–specific binding, lowering false positives without rejecting true positives

Genova Diagnostics offers two Allergix® IgG4 Food Antibody Profiles:

  • IgG4 Food Antibody Profile – measures serum levels of IgG4 antibodies specific to 90 food antigens. A four–day rotation diet is included.
  • Bloodspot IgG4 Food Antibody Profile – measures levels of IgG4 antibodies specific to 30 common offending foods from an easy–to–use finger stick. A four–day rotation diet is included.

Special Pricing is available for the following combination profile:
