Next Generation in Food Sensitivity Testing
Breakthroughs in IgG Antibody Testing!
- New patent pending IgG4 assay
- First test to quantitate IgG4
- Eliminate non-specific binding therefore eliminate false positives without rejecting true positives!
Allergix™ Bloodspot IgG4 Food Antibodies*
IgG antibodies are associated with non-atopic or "delayed" food reactions that can worsen or contribute to many different health problems. Food sensitivities can occur at any age, triggering many different symptoms and contribute to a variety of disorders.
From a simple finger stick, the Allergix™ Bloodspot™ IgG Food Antibody Profile measures levels of IgG antibodies specific to 30 commonly offending foods. It clearly identifies 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
- Migraines
- Skin problems
- Rheumatoid arthritis
- Sinusitis
- Recurrent ear infections
*Bloodspot profile not available in New York

- Easy to implement in any practice
- Does not require venipuncture
- Cost-effective testing & therapy
- Easy enough that patients can even do it at home
- Simple and economical option for follow-up testing
