IgG Food Explorer – What You Need to Know

Diagnostic Solutions logo

The IgG Food Explorer™, developed by Diagnostic Solutions Laboratory, is a multiplex food sensitivity test that measures total IgG antibodies to a wide array of foods. It aims to alleviate symptoms associated with adverse food reactions and promote personalized patient care. With over 250 food antigens evaluated through a convenient at-home collection (or a blood draw), this test provides valuable insights for practitioners to customize diet and lifestyle recommendations.

Are Food Sensitivities Causing Your Patient’s Uncomfortable Symptoms?

Food sensitivities are an adverse immune reaction to an ordinarily harmless food. Symptoms vary greatly from person to person and are usually  delayed, making them hard to pinpoint without testing. Common symptoms include, but are not limited to:

  • Gastrointestinal complaints, including bloating, nausea, diarrhea and IBS
  • Irritable Bowel Syndrome (IBS)
  • Autoimmune conditions
  • Skin symptoms, such as atopic dermatitis, eczema, and rashes
  • Headaches
  • Joint Pain
  • Mood disorders, including anxiety, ADHD and more


Evaluates over 250 Foods

The IgG Food Explorer evaluates a comprehensive list of foods and spices to see what foods trigger your patient’s symptoms.

Molecular antigens for wheat gliadin and cow’s milk are also included for enhanced insight into the sensitivity of those potentially immunogenic foods.

Food Sensitivities and Gut Health

IgG-mediated food sensitivities frequently occur due to compromised gut health, impaired digestion, dysbiosis, and inflammation. These factors can contribute to intestinal permeability, commonly known as “leaky gut.”


In cases where a patient exhibits a strong reactivity in a food sensitivity test, it is recommended to conduct follow-up GI-MAP testing.
