What we do: In our hair labs we provide bioresonance testing using MARS III technology. In our blood labs, we use a blood testing system which operates in a very similar way to ELISA as used by the market leaders. Using a variation on a blotting procedure, the lab technicians at TMI Testing can test your blood’s IgE (allergy) and IgG4 (intolerance) levels against specific allergens. Raised levels of IgE are indicative of an allergy whereas raised IgG4 levels are used as an indicator of food intolerances.

Our Business Ethos

Informed decision making

We offer a broad and diverse range of testing covering both conventional and alternative methodologies. We do this to ensure clients are given the best possible choice whilst receiving the key facts about each product.

Customer service

We believe in treating customers fairly and effectively. We offer a 100% money-back guarantee on our alternative therapy products and a no reaction, no charge promise on our home-to-lab blood testing. Our business follows a core customer service strategy utilising Salesforce to ensure your contact with us is well documented and secure. In the unlikely event that you have an issue with our service, we have a complaint handling procedure designed to ensure a fair and consistent resolution for clients.

Privacy and data

We use secure dedicated servers to ensure your privacy and confidentiality at all time. Our employees are restricted to the information and advice they may provide to a client by internal protocols designed to protect both you and our business. All confidential documentation is processed by our nominated ISO approved confidential waste company. All waste from samples is also disposed of as medical waste and incinerated by the same company.

Environmental impact

The majority of our suppliers provide packaging that is either fully or partially recyclable and using plant-based ink. Our facilities use recycling of non-confidential waste, reduction in energy usage through energy-saving or efficient devices and we are moving to suppliers of essential services such as energy, waste disposal and consumables that are either carbon neutral or from renewable sources.
