Medix Biochemica’s Vision and Values

Medix Biochemica's vision is to be the foremost raw material partner for the IVD sector. With various distinct focuses and core capabilities across our sites, we strategically drive innovation, quality and provide tailored solutions to meet the diverse demands of IVD manufacturers.4

Our comprehensive portfolio continues to grow in breadth and depth, now offering a wide range of cutting-edge diagnostic reagents, immunoassay components and raw materials for vital IVD technologies. In fact, in November 2023, we announced the acquisition of US-based ViroStat, which significantly strengthens our offerings in the area of infectious diseases.4 

Quality and reliability are at the heart of what we do, and this benefits our customers at every stage of production. By using multiple high-quality, thoroughly tested raw materials from Medix Biochemica, our customers are able to get their finished products to market quickly and efficiently.2

Our dedication to quality, consistency and continuous growth means that we are able to empower the IVD manufacturers we partner with, positioning them at the forefront of accuracy, reliability and innovation in diagnostic testing.4


Medix Biochemica’s History

In 1984, the Nobel Prize in Physiology or Medicine was awarded to César Milstein, Georges J.F. Köhler and Niels Jerne for developing the hybridoma method of producing monoclonal antibodies.5 Medix Biochemica was founded in Finland shortly afterwards, in 1985, and was the first company of its kind to sell high-quality monoclonal antibodies on an industrial scale.2

Since then, we have grown and expanded to make this technology accessible across the world,2 making important strategic acquisitions that have helped us expand our portfolio and offerings to clients.2,6
