Food Antibody Testing
IgE
The less common but widely recognized atopic food sensitivities, such as an immediate reaction to peanuts or shellfish, are IgE-mediated responses.
IgG4
IgG4 antibodies are associated with non-atopic or "delayed" food reactions that can worsen or contribute to many different health problems and are considered the most common form of immunologically mediated food intolerance. 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 may eat a food for several days before developing a reaction to it, so they may not realize the link between the food and their symptoms. These "hidden" food allergies are caused by increasing blood levels of IgG4 antibodies in reaction to specific foods. Often the offenders are frequently eaten foods that are hard to avoid, such as milk, corn, and wheat. Simultaneous high levels of many IgG food-specific antibodies are generally related to intestinal hyperpermeability.
Bloodspot IgG4*
From a simple finger stick, the Bloodspot™ IgG4 Food Antibody Profile measures levels of IgG4 antibodies specific to 30 commonly offending foods. It clearly identify those foods that may be causing health problems, helping to achieve positive outcomes sooner, even when combined with elimination/provocation testing.

Food sensitivities can occur at any age, triggering many different symptoms and contributing to a variety of disorders, including:
- Inflammatory bowel disease
- Fatigue
- ADD/ADHD
- Migraine
- Skin problems
- Rheumatoid arthritis
- Sinusitis
- Recurrent ear infections
Metametrix offers a choice of testing:
-
IgG4 Food Antibody Profile, which measures serum levels of IgG antibody subclasses 1 and 4 specific to 90 food antigens. A customized, 4-day rotation diet is included.
-
Bloodspot™ IgG Food Antibody Profile*, which measures levels of IgG antibodies specific to 30 commonly offending foods from a finger stick. A standard 4-day rotation diet is included.
-
IgE Food Antibody Profile, which measures levels of antigen-specific IgE to 30 common foods from a serum specimen.
-
Special pricing when you order serum IgG and IgE food antibody testing together.
