Food Sensitivity Testing

IgG Food Sensitivity Blood Test 

Food intolerance is all about how your body’s immune system, its natural defense against harmful foreign substances, reacts to specific foods. Food intolerances arise when certain, incompletely digested food particles enter your bloodstream and are treated as foreign substances. This results in your immune system producing tailor-made antibodies called Immunoglobulin G (IgG), which attack the food in question. Researchers demonstrate that this inflammatory response in the body can increase certain symptoms such as Irritable Bowel Syndrome (IBS), bloating, tiredness, constipation, diarrhea, cramping, eczema, headaches and migraines.

The IgG Food Sensitivity testing is available as a dried blood spot collection.

This is an easy finger prick for patients and only takes a minute during an office visit. No blood draw is necessary offering a non-invasive, easy procedure that offers a wealth of information about how foods are impacting your body.

Once the doctors discover your nutritional needs through state-of-the art testing, a specific nutritional plan will be made for you. The nutritional plan can include the elimination of certain foods from your diet, and the introduction of specific nutritional supplements to support the needs of your body.

The Key to Understanding Your Food Sensitivities. 

Do you ever feel like you may have certain symptoms related to foods, such as headaches, stomach pain, diarrhea, or fatigue? You want to try eliminating possible triggers, but you are not sure where to start?

Our Food Sensitivity tests measure your body’s immune response to 185 foods that are commonly found in western diets.

Unlike a life-threatening food allergy or severe medical conditional like celiac disease, an antibody IgG immune response has been demonstrated to offer guidance on what foods may be the best to eliminate first. Rather than randomly eliminating foods over many months and assessing your change in symptoms, as improvement in symptoms is always the best test, you can have a directed elimination plan. This test is not a food allergy test. Food allergy tests measure IgE antibodies, which require a larger volume of blood and thus can’t be currently taken at home. Food sensitivity testing also cannot diagnose Celiac Disease.
