H&D srl

We are a diagnostics company focused on measuring oxidative stress.

H&D was founded in 2003, gathering the great experience of its founder, Dr. Fabrizio Callegari who since the beginning of the 90s, began to be interested in studying and analyzing, with a scientific method, the issues relating to oxidative stress, developing the first tests for its measurement.

H&D, continuing to follow the same path, has invested its energy to improve the results obtained and develop new products capable of offering the best possible result.

The tests are used by more than 2.000 researchers worldwide with more than 800 scientific publications.

We are committed in offering an effective and safe tool for measuring oxidative stress according to the high standards that the range requires today.
We believe that the customer is at the center of our work and we constantly strive to offer not only a quality product but also constant support from a scientific and technical point of view.

Continuous innovation, patents created, intuitions, team work, quality certifications allow us to guarantee an ongoing growing standard of excellence.

We want to become an authoritative reference point, create global awareness in the field of oxidative stress and offer high quality available worldwide.
