Regenerus launches the IgG Food MAP from Great Plains Laboratory

Regenerus launches the IgG Food MAP from Great Plains Laboratory

We are excited to announce that we’ve launched the IgG Food MAP from Great Plains Laboratory, and it is available to purchase from our website from today.

Measure your patient's IgG reponse to 190 foods in one accurate, reliable, convenient and eco-friendly test

The IgG Food MAP measures the body’s IgG response to 190 foods, as well as Candida albicans and yeast (Saccharomyces Cerevisiae).

Why is it worthwhile testing for IgG food sensitivity in patients?

Research shows that IgG-positive foods cause adverse immune reactions that contribute to many chronic health conditions, including:

  • irritable bowel syndrome
  • cystic fibrosis
  • rheumatoid arthritis
  • epilepsy
  • Autism Spectrum Disorders
  • ADHD
Using this test will enable you to identify if, and which, foods are causing IgG-positive responses in your patients, and therefore which they should remove from their diet.


Many clinical studies have proven that the withdrawal of IgG-positive foods improves chronic health conditions, including those listed above.

Removing the offending food reduce stress on the immune system, decreases inflammation and healing leaky gut.

More benefits of testing IgG food sensitivity in patients

IgG testing determines if IgG food sensitivities are contributing to health conditions much quicker than removing and reintroducing suspect foods one-by-one.

Removing highly reactive foods from a patient’s diet is a non-invasive way of alleviating patient symptoms.


Undiagnosed patients are unlikely to recognise that eating certain foods are causing IgG reactions, and consequently, their symptoms. This because, unlike IgE antibodies, which cause an immediate immune reaction, IgG immune reactions appear anywhere from hours to days after eating the offending food

When should this test be used?

Clinicians should use this test when they suspect that patients are having immune reactions to certain foods, particularly when they are displaying neurological, gastrointestinal, movement, and behavioural symptoms.

Why use the IgG Food Map to test for IgG food sensitivity instead of any other IgG food test?

Increased Accuracy and Reliability of Results

Great Plains’ research has proven the IgG Food Map to be more precise and reliable than standard ELISA tests.

This is due to the IgG Food Map’s immunofluorescent bead technology, as its innovative approach of combining food antigenic proteins with beads is able to identify IgG food antibodies with much more specificity.

Significantly more time, effort and ecologically efficient

Great Plains’ research has proven the IgG Food Map to be significantly more time, effort, and ecologically efficient than a standard ELISA. Specifically, they argue that it requires:

  • less sample volume requirements and reagent
  • less lab time and equipment to analyse
  • less difficulty to perform and reproduce
Again, this is due to the IgG Food Map’s immunofluorescent bead technology, as its multiplexed bead-based assay is able to simultaneously analyse hundreds of analytes at once.


To clarify, to analyse an ELISA panel of 190 foods requires 190 wells per sample.

In contrast, the IgG Food Map only requires two wells per sample, being able to simultaneously detect all 190 foods’ IgG antibodies.

Furthermore, Great Plains has fully automated every step of this test process.

Very easy, convenient and stable sample collection required

As the IgG Food Map only requires five dried blood spots, sample collection is simple quick, easy, cost-effective and non-intrusive for your patient. In contrast, it avoids them having to arrange, endure and pay for a costly blood draw.

As the sample life is a robust 21 days from collection to lab, their is no high-stakes deadline to get the sample to the lab, meaning reduced administrative demand on your patient, as well as reduced likelihood of sample invalidation.

As the IgG Food Map directs the patient to eat as normal for 3-4 weeks, collecting the sample on the 33-36 day, sample collection does not intrude on the patient’s daily life.
