We develop, manufacture and distribute high quality in vitro diagnostic reagents and vaccines.

Rapid diagnostic test kits for MRSA, E. coli O157, parvo B19, norovirus and influenza viruses are also market leaders in many countries around the world. Denka Seiken possesses numerous collaborative business relations with world-wide top ten diagnostic companies, and has ISO13485 and ISO14001 certification as well as a number of products FDA-cleared for sale in the US.

In 2003 Denka Seiken established its first international branch office in the UK to assist in the promotion of its extensive line of diagnostics reagents for clinical chemistry and infectious disease testing. The US branch office was established in the following year, complementing the UK office for promotional marketing activities, setting up of clinical trials and new product evaluations, and providing FDA-related regulatory support to the head office.
