Business Overview

The Diagnostics Business Group serves as the core business of our company. We mainly develop, manufacture and market in vitro diagnostics for hospital laboratories and clinical test centers. As a pioneer of biochemical testing, Sekisui Medical has always played a leading role with regard to in vitro diagnostics for the biochemical sector. In particular, the originality of the core technologies we apply in the lipids field keeps us way ahead of our competitors. The reagents we have developed to directly measure HDL-C and LDL-C hold the top market share both in Japan and overseas.

In recent years we have also launched a new latex reagent created by combining diagnostics development techniques (LTIA method) with latex technology that is based upon microparticle technology.
Our product lineups focus on four key areas (biochemistry, blood coagulation, diabetes and infectious diseases), and we aim to win the top market share in each of these sectors. In addition, we are expanding our lineup of specialized analyzers in each key area. We offer a comprehensive system of diagnostics and analyzers to meet a wide range of customer needs.
