We are global leader in the laboratory diagnostics market, specializing in the immunodiagnostics and molecular diagnostics segments.


For over 50 years we have been dealing with diagnostics to help physicians and patients make better decisions in the most important moments.

Diagnosis is, in fact, the first step to become aware of a person’s state of health: this is why our tests can make the difference. Their precision and reliability allow the early diagnosis of different diseases for millions of people, who will be able to undertake the appropriate clinical pathway.

A global reality

We are a multinational company operating across 5 continents.

Our headquarters are in Saluggia, and the Group production platform involves 6 manufacturing plants around the world.

Our research and development centers are based in Italy, USA and Germany.
