In 1972, GCMS started with the introduction of the first blood grouping. For the past 40 years, we have been accumulating high technology and know-how in the field of medical devices and diagnostic reagents. We have proved ourselves as a matchless ‘Total Medical Device Company’ through aggressive business diversification such as blood glucose business, kidney hemodialysis business, and blood bag business with application of our know-how in in-vitro diagnostics.
