History

Werfen traces its origins to 1966, when José María Rubiralta founded Izasa in Barcelona as a privately owned distributor of clinical diagnostic products. The company’s official history identifies this as the foundation of what later became Werfen. Its early development included moves from distribution into manufacturing and scientific instrumentation: Biokit was founded in Barcelona in 1973, and Instrumentación Científica was founded there in 1974. The history also records geographical expansion into Latin America in 1979 and the founding of Leventon, marking an entry into medical-device manufacturing. A major step in building Werfen’s specialized diagnostics business came in 1991 with the acquisition of Instrumentation Laboratory, identified by the company as a global leader in Hemostasis and Acute Care Diagnostics systems. In 1996, Werfen acquired Chromogenix in Sweden and Mallinckrodt Sensor Systems in the United States, expanding its Hemostasis and Acute Care activities. The 1999 acquisition of Hemoliance further strengthened its position in Hemostasis. The company broadened its diagnostic areas through acquisitions in the following decade. In 2008, it acquired Inova Diagnostics, which its history describes as a leader in Autoimmunity Diagnostics. In 2009, it acquired the autoimmune diagnostics business of The Binding Site Ltd. The company inaugurated Torre Werfen as its new Barcelona headquarters in 2011. Its official history page also lists a 2012 generational change, although the supplied page excerpt does not provide further details. Werfen describes itself as a growing, family-owned company and a worldwide leader in specialized diagnostics. It reports direct operations in 30 countries and distributor coverage in more than 100 territories, with headquarters in Barcelona and Technology Centers in the United States and Europe. Its current areas of expertise include Hemostasis, Acute Care Diagnostics, Transfusion, Autoimmunity, and Transplant. In October 2024, Werfen completed the acquisition of Omixon, a privately held Budapest-based company focused on next-generation sequencing technologies in transplant diagnostics. Werfen reported almost €2.2 billion in worldwide sales and a workforce of 7,000 in 2024.
