This easy-to-use blood-spot test will provide valuable information on food and environmental factors covering potential allergies and food intolerances. If you suffer from symptoms including itchy eyes, bloating, headaches, nausea or IBS this test will help you identify potential allergies or food intolerances.

Our expert team of intolerance 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.

What your test will include:

• 40 common food intolerances including Dairy, Egg, Meat, Wheat, Fish and Vegetables.
• 38 common allergens including Pollens, Nuts, Grains, Dairy and Pet Dander.
• A CE and UKCA-approved blood-spot collection kit shipped free and including a free return envelope.
• Results processed in our labs in 3-5 business days and sent direct to you.

No-risk money-back guarantee:

All of our Allergy and Intolerance Testing includes a money-back guarantee if your results show no reaction. This means if you receive your validated results and the test has found no raised IgE or IgG4 levels against the items we test, you will receive a full refund allowing you to continue your health journey without being out of pocket.

How the intolerance test works:

Using ELISA testing for raised IgE (allergy) and IgG4 (intolerance) antibodies, this blood spot test offers accurate lab results to enable you to adjust your diet to reduce or avoid triggers.

Raised IgE (immunoglobulin E) antibodies are a recognised indicator of an allergy reaction. IgE allergy reactions are usually less common than intolerances (IgG4) and present as a more immediate reaction.

Raised IgG4 (Immunoglobulin G) antibodies can indicate a food intolerance. IgG4 responses are more common than IgE (allergy), which causes an immediate reaction. Food intolerance reactions can be more difficult to self-diagnose since symptoms can occur hours or even days after consumption of an offending food.

Food Intolerance and Allergy Symptoms:

Our combined allergy and intolerance testing 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 allergies and intolerances on our website.

Food intolerance symptoms 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

Discover if food intolerances or allergies are the causes of your symptoms in this fast and easy-to-use combined allergy and intolerance test. Use the results to help you eliminate triggers and adjust your diet and lifestyle.

All of our blood kits are UKCA and CE marked.

The UKCA and CE markings are labels to display that our blood kits comply with regulatory requirements.

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 & Intolerance test 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 that 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.

• Raised IgE values prove clinically significant in identifying an IgE-Mediated Allergy.
• Removal of raised IgG4 items may improve lifestyle based on testimonial evidence.
• Testing is carried out in a variety of locations worldwide.
• CE approved sample collection kit.
• Results do not constitute a medical diagnosis on their own, but may be used by your doctor or nutritional therapist to help form a diagnosis or rule out a condition.
• Quantitative data using an ELISA testing methodology. All values measured in Kilounits per antigen per litre (KUA/L), our scale uses a universal cut off point of 0.35 in classifying a reaction.
• >97% reproducible results. IgG4 values may change over time with diet.

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).

All information in the reports produced is intended to support nutritional advice to optimise your diet. The results cannot be used to diagnose, treat or cure medical/health conditions.

The use of antihistamines prior to or during the blood sample collection process may affect your results, please contact our team for further advice.
