Allergy & Intolerance Test Plus

Our combined Allergy and Intolerance Plus Test is our most comprehensive and accurate test of 117 common triggers of allergies and food intolerances. A fast and cost-effective way of screening that uses ELISA testing for raised IgE and IgG4 antibodies, this test offers accurate lab results to enable you to adjust your diet and lifestyle to reduce or avoid triggers.

Results are then delivered via one easy-to-understand report. The personal allergy and food intolerance report includes the following key elements:

– Explanations of the testing process.
– IgE reactions to items screened.
– IgG4 reactions to items screened.
– Elimination diet recommendations.

Our expert team of allergy and intolerance lab technicians and lab managers have over 20 years of combined experience in allergy & intolerance testing and work from our category 2, ISO9001 accredited Allergy and intolerance testing laboratory.

The Science Behind Allergy and Intolerance Testing

Using ELISA testing for raised IgE antibodies to detect 38 allergies and 40 IgG4 antibodies to detect food intolerances, this test offers accurate lab results to enable you to optimize your diet and lifestyle. By testing both IgE and IgG4 antibodies, we give you a more comprehensive understanding of possible causes of symptoms, aiding more effective elimination or further investigation.

How to Test for Allergies

Raised IgE (immunoglobulin E) antibodies are a recognized indicator of an allergy reaction. IgE allergy reactions are usually less common than intolerances (IgG) and present as a more immediate reaction.

How to Test for a Food Intolerance

Raised IgG4 (Immunoglobulin G) antibodies indicate you have a food intolerance. IgG4 responses are more common than IgE (allergy), which causes an immediate reaction.

How Our Allergy and Intolerance Plus Test Works

What’s tested?

Food Intolerances, food allergies, and inhalant allergies. Including common allergy and intolerance triggers such as eggs, grains, fruits, meat, wheat, insects, pet dander, pollens, and fish.

Purchase and Delivery

Following the simple and secure payment process, you will receive free delivery of our CE-approved sample collection kit within 6 – 9 business days including easy instructions on how to complete your test.

Sample and Results Explained

Just a few spots of blood are required using a pin-prick lancet within the kit. Send everything to our labs in the envelope provided, and we’ll do the rest. We notify you when your sample arrives, and you will receive results from our lab to your email and our app in under 7 days.

Also Included:

• A full guide on how to perform an elimination diet of reacting items.

Food Intolerance and Allergy Symptoms

Our combined allergy and intolerance plus test can help you identify the triggers related to digestive symptoms associated with food intolerances and other more immediate symptoms related to allergies. Depending on whether you have an allergy or intolerance, you will experience different symptoms. You can read more about these differences between food allergies and intolerances on our website.

Symptoms of food intolerance include:

• Bloating
• Fatigue
• Nausea
• Stomach cramps
• Diarrhoea
• Migraines
• Itchy eyes

Further symptoms you may experience if you have an allergy include:

• Mouth swelling
• Breathing difficulties
• Vomiting
• Skin rashes

Get a comprehensive analysis of food intolerances or allergies to understand if they are the causes of your symptoms in this fast and easy-to-use combined test. Use the results to help you eliminate triggers and adjust your diet and lifestyle effectively.

How to take your sample

The Science

This test uses the IgE and IgG4 in your blood sample for intolerance and allergy testing, but what does that mean?

At Test Your Intolerance, we’re proud to offer the possibility to test for both IgE and IgG4. Our Allergy and Intolerance Test Plus offers both immunological and non-immunological responses, giving you a full overview of your body and the more specific reactions caused when you are fighting foreign substances via antigens.

Why IgE and IgG4?

The interpretation of the IgE:IgG4 ratio is useful to determine the possibility of an allergic reaction. If it is higher, there is a high likelihood of an allergic reaction occurring, whereas the low ratio shows a low-grade allergic reaction. To identify food allergens which cause chronic inflammatory diseases, it’s required to test the total IgG, whereas IgE is determined only in presence of a Type I or Type 1 allergy. Scientific studies have shown that people with inflammatory and alimentary intolerance have had IgG directed against food antigens alone, but not IgE. An elimination diet elimination based on IgG antibodies (elimination of food with high IgG/IgG4 levels) as demonstrated great ability to manage symptoms in people with IBS and migraines.

We are not offering a quick solution, but the possibility to map out your body like never before. Our range of tests are not used for the diagnosis of chronic or acute food allergies or intolerances as explained in our Test Facts. The easy-to-understand test results report can be combined with your medical history and the help of your GP or an allergist to start this journey for a better version of yourself.

Important

Blood (ELISA) tests define an intolerance/sensitivity as a specific IgG4 antibody reaction and an allergy as a specific IgE antibody reaction (IgE-Mediated).
