Innovation: one of our main pillars

Diater products are the result of our profound knowledge of allergen extracts, our continuous use of the most innovative techniques and our rigorous manufacturing process. Our mission to innovate and develop new diagnostic and therapeutic solutions is reflected in our constant flow of new products intended to improve medical practice and wellbeing in patients with allergies.

We help to improve the health and quality of life of people with allergies by providing novel diagnostic and therapeutic tools that facilitate specialist medical practice and improve patient quality of life.

Diater has been committed to innovation in allergic diseases ever since it was founded. Diater has first-class R&D facilities and collaborates in various efforts with centres of excellence in Spain and elsewhere.

Internationalisation as a vector for growth

Diater has become well established in Spain since it was founded there in 1999. A few years ago, it initiated a significant internationalisation process to offer our diagnostic and therapeutic solutions to more specialists in allergic diseases.

Building long-term relationships with our partners in different parts of the world is key and essential to achieving this goal and making our products accessible to more patients.
