About Us

Test Your Intolerance is part of the Worldwide Health & Wellness company, Healthy Stuff Online Ltd.

We have been offering wellness services to clients and partners since 2008. The business started with complementary and alternative medicines (CAMs), providing help and support to those that had exhausted conventional health paths. We rapidly developed a more extensive range of tests to include those that were scientifically supported and products from trusted brands.

Our global network of websites and partners now reaches over 40 countries providing allergy, intolerance, sensitivity, DNA and other health-related tests to clients.

We remain committed to our core belief that individuals should be presented with the relevant key facts relating to tests available to them and from those key facts they can make an informed decision on which path to take.

This is why we continue to offer both conventional and complementary products and services, therefore, offering the most comprehensive choice to a potential client. All our tests have a ‘Test Facts’ statement giving you the essential relevant information about the test. We were the first company to create and implement this useful aid in ensuring clients understand the test they are buying in November 2019.

Our head office and laboratories are located in Derby, United Kingdom. The labs follow Good Laboratory Practice and our state-of-the-art allergy and intolerance lab is part of a facility certified according to ISO 9001. We continue to invest in the latest equipment and training to ensure we provide our customers with the best possible service.

We have a full compliance procedure that is adhered to for all testing. If you need to contact us about this, please use [email protected]


Choice of convention

As an organization, we believe that not one size fits all. For some, conventional products and services offer the very best choice; for others, they may have exhausted those options. By giving our clients relevant information to make an informed decision, we believe we offer the widest and most diverse forms of testing.


We use a dedicated secure server to host our websites and transactional infrastructure. We also have our own CRM system ‘HealthSuite’. Our team is regularly trained and audited for data protection compliance, and we adopt an access protocol to ensure data is not shared or accessed by individuals that lack the correct authority. All confidential documentation is processed by a confidential waste company. All waste samples are also disposed of as medical waste and incinerated.


As a business, we continue to grow our team through the combination of high calibre recruitment and internal training. Our laboratories and technicians are headed by microbiologist Kate Young and our medical development manager Dr Enzo Fornari. All employees receive continuous training and recording plan and opportunities to develop skills in new and exciting fields. To meet the whole management team, click here to visit Healthy Stuff

Environmental responsibility

All of our box packagings are now recyclable and uses plant-based ink. Our offices and labs use recycling of non-confidential waste, and we promote the use of energy-saving devices throughout the business. Our goal is to move to suppliers of essential services such as energy, waste disposal and consumables that are either carbon neutral or from renewable sources.


Our Strongest asset is our people. This is not limited to the people who work with us, but the clients we help. That value underpins our customer obsession to treat customers fairly, professionally and with care. That is why we have a customer promise, satisfaction guarantee and offer a range of support structures for clients.


We offer our clients the opportunity to review our products and services through our partner, TrustedShops, and through our customer survey. Both provide us with invaluable feedback on how we are performing for you. We only use and endorse these methods of customer reviews as they require a full purchase and customer journey to be completed. Therefore, every independent, anonymous review is from a client who has experienced the same as you.
