Allergies & Intolerances

Allergy and Food Intolerance Testing

The body produces different types of immunoglobulins, or antibodies, in response to foreign substances such as foods, allergens, and environmental triggers. Understanding the differences between antibodies such as IgE, IgG, and IgA can help healthcare practitioners select the most appropriate test based on a patient’s symptoms and clinical history.

NutriPATH’s Allergies & Intolerances testing helps assess immune responses to foods and allergens, providing useful information for practitioners evaluating symptoms that may be related to food allergies, food sensitivities, or food intolerances.

Understanding IgE, IgG, and IgA

IgE is commonly associated with immediate allergic reactions. These reactions may occur shortly after exposure to a food or inhalant allergen and may involve symptoms such as rash, hives, itching, swelling, wheezing, or in some cases, severe allergic reactions.

IgG is often associated with delayed food sensitivity reactions. Symptoms may appear hours to days after exposure to a food or inhalant allergen, making it more difficult to identify potential triggers through observation alone.

IgA is commonly found in mucosal areas of the body, including the gastrointestinal tract and respiratory system. IgA testing may help practitioners assess immune responses related to mucosal health and certain food-related reactions.

What Can Allergy and Intolerance Testing Help Assess?

Allergy and intolerance testing may support practitioner assessment of symptoms and concerns such as:

• Bloating, abdominal discomfort, or digestive symptoms
• Diarrhoea or irregular bowel habits
• Rash, hives, or skin reactions
• Headaches or migraines
• Chronic fatigue
• Symptoms associated with irritable bowel syndrome (IBS)
• Suspected delayed food sensitivity
• Respiratory symptoms related to environmental allergies, such as wheezing or asthma-like symptoms

NutriPATH Allergy and Intolerance Test Options

NutriPATH offers a range of allergy and intolerance testing options, including food antibody panels, IgE testing for immediate allergic reactions, IgG testing for delayed food sensitivity reactions, and IgA testing related to mucosal immune responses.
Examples of available tests include:

• Allergy Panels - IgE General Foods
• Allergy Panels - IgE Inhalants
• Allergy Panels - IgE Moulds
• Allergy Panels - IgG General Foods
• Allergy Panels - IgG Asian Foods
• Allergy Panels - IgA General Foods
• IgE & IgG General Western Food Panel
• IgG & IgA General Western Food Panel
• IgG/IgA Complete Food Panel
• Total Immunoglobulins

These tests may help reduce the uncertainty of trial-and-error food elimination and provide more structured information for practitioner-guided dietary and health planning.
