About Us

healthystuff logo - About Us

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

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

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

We remain committed to the belief that people should be presented with the key relevant facts relating to tests available to them. And from these key facts, individuals can make an informed decision on which direction to take.

This is why we continue to offer conventional and complementary products and services. It allows us to provide the most comprehensive choice to a potential client or customer. All of our tests have a ‘Test Facts’ statement giving site visitors all essential and relevant information about each test. We were the first company to implement this invaluable aid in November 2019 to ensure clients understand the test they are buying.

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

Choice of convention

As an organization, we understand that one-size-fits-all doesn’t always work. For some people, conventional products and services offer the very best selection; but others may have exhausted those conventional options. By giving our clients relevant information to make an informed decision, we believe we have the most extensive and most diverse offering.


We use a dedicated secure server to host our websites and transactional infrastructure. We also use Salesforce to store all client data and communications. 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. A confidential waste company processes all confidential documentation. All waste samples are disposed of as medical waste and, therefore, 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 Wooster 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 recycle non-confidential waste. We also promote the use of energy-saving devices throughout the business. We aim to move to carbon-neutral suppliers or renewable sources of essential services such as energy, waste disposal and consumables.


Our Strongest asset is our people. This is not limited to our employees, but the clients and partners we help. This value underpins our obsession to treat our customers fairly, professionally and with care at all times. That is why we have a satisfaction guarantee, customer promise and have a range of support structures in place for customers.


Each of our clients is given the opportunity to review our products and services through our customer survey. This provides us with invaluable feedback on how we are serving our clients. We only use and endorse these methods of customer reviews as they require a full purchase and the customer journey to be completed. Hence, every single independent, anonymous review is from a client who has experienced the same as you.
