Metametrix: Allergix IgG “Delayed” Food Allergy Response

IgG4 antibodies are associated with non-atopic or "delayed" food reactions that can worsen or contribute to many different health problems. These reactions are considered the most common form of immunologically mediated food intolerance. An IgG4 response to food is actually more common than the IgE response, which causes an immediate reaction. IgG4 acts as a blocking antibody, protecting the individual from potentially fatal IgE reactions. These 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 caused by increasing blood levels of IgG4 antibodies in reaction to specific foods.

Food sensitivities can occur at any age, triggering many different symptoms and contributing to a variety of disorders including:
Inflammatory bowel disease, Gas/bloating, Fatigue, Mood swings, ADD/ADHD, Headaches/Migraines, Skin Problems, Rheumatoid arthritis, Sinusitis, Recurrent ear infections.

Metametrix Innovation in IgG Antibody 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

Common offending frequently eaten foods typically hard to avoid:
milk, corn, wheat, egg, foods processed with mods such as black tea, breads and fruit juices.

Metametrix 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 commonly offending foods from an easy-to-use finger stick. A four-day rotation diet is included.
  
  Special Pricing is available for the following Allergix combination profiles:
   IgG4 and IgE Food Antibodies
   IgG4 Food Antibodies and Celiac Profile

Special Note on Gluten:Gluten intolerances begin in the stool or in the saliva and show up last in the blood. When a gluten intolerance shows up in the stool or saliva and a gluten free diet is then followed,  it can be a way to prevent Celiac.  Since it is possible to test negative for all of the gluten grains but positive for a gluten intolerance we suggest combining the “Allergix” blood tests with a gluten/leaky gut stool or saliva test.

Test results include a full color Food Reaction Patient Guide which will provide information on how to interpret your results, build your own customized, 4-day rotation diet, dietary recommendations, and alternative food options.
