About Test Your Intolerance Allergy and food intolerance testing

Test Your Intolerance are the worldwide leader of allergy and food intolerance testing offering the widest choice of tests in the market.

Our exclusive tests are performed at our purpose-built laboratory that forms part of our head office facilities and uses state-of-the-art in-vitro diagnostic equipment.

Using IgE and IgG4 for testing

The interpretation of the IgE:IgG4 ratio determines 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.

Scientific studies have shown that people with inflammatory and alimentary intolerances have had IgG directed against food antigens alone, but not IgE.

An elimination diet based on IgG antibodies (elimination of food with high IgG/IgG4 levels) has demonstrated outstanding ability to manage symptoms in people with IBS and migraines.

Our easy-to-understand test results can be combined with your medical history and, with the help of your GP or an allergist, you can start your journey for a healthier you!

How does it work?

The allergy IgE Kit used to detect specific IgE (human) is a cost-effective and reliable laboratory test that uses enzyme immunoassay for in-vitro allergy diagnostics inline strip format.

The assay is used for the semi-quantitative determination of specific IgE antibodies against a selection of relevant allergens for the serological diagnosis of type 1 allergies (immediate type) in patients. Multiple panels of inhalation and food allergens are available.

The IgG4 Intolerance test kit uses enzyme immunoassay (ELISA Technology) and consists of designed nitro-cellulose-based line strips to detect specific IgG4 antibodies. The assay is reliable, fast, and cost-effective. Multiple food panels and sizes are available.

The processing of your sample

The laboratory and team of qualified lab technicians are managed by the laboratory manager, Kate Young, a microbiologist with years of experience providing accurate and consistent diagnostic results.

When your sample arrives at our lab, the item is checked in and linked securely to your account. At this point, you will receive a notification that the testing process has started. The sample is batched and passed to the blood testing lab, where a technician will extract the whole blood sample.

Cutting-edge lab equipment

The samples are then placed in a centrifuge to extract the plasma. The plasma is then used against various allergen strips, and the resulting reactions are read by cutting-edge lab equipment. These results are then quality checked and compiled into a report sent to your email and the Healthy Stuff app.

A clinical waste disposal company then disposes of your sample. Our confidential waste provider destroys any documentation submitted to use with your sample to protect your data.

Client records are maintained on our secure service provider, powered by our bespoke platform, following stringent data processing procedures & GDPR.

Our testing equipment

Our global allergen supplying partners, DST, are certified according to ISO9001:2008 and ISO13485:2016, providing us with equipment and allergens to deliver accurate and reliable results to our clients.

The team of scientists at DST have worked closely with us to develop an exclusive range of tests that offer a wide range of diagnostic results to varied budgets.

Alongside the Autoblot 3000 machines, our labs use the Helia system, a fully automated analyser for line immunoassays.
