GC Biopharma MS was established in 2003 with the business purpose of manufacturing and selling in-vitro diagnostic reagents and medical devices, and is an affiliate of the GC Group (formerly Green Cross Group), with GC Biopharma (Green Cross Corp.) as its largest shareholder.
The company's business is centered on diagnostic reagents, dialysis solution, and blood glucose/diabetes-related products; as of 2025, the revenue mix was approximately 52% diagnostic reagents, 29% dialysis solution, 15% blood glucose, 2% home healthcare, and 2% other, with diagnostic reagents and dialysis solution together accounting for more than 80% of revenue.
The blood bag business, formerly one of four core segments, was spun off and divested in May 2020, reshaping the company into its current structure.
The company maintains a wide domestic sales network supplying public health centers, screening centers, internal medicine, dermatology and plastic surgery clinics, hospitals, general hospitals, and university hospitals.
Overseas, it exports diagnostic reagents and medical devices to the United States, Russia, Africa, Latin America, the Middle East, and across Asia, pursuing expansion as an export-oriented global medical device company. Management changed in March 2025, with CEO Sakong Yeong-hee replaced by CEO Kim Yeon-geun.
Under the standard industry classification for medical supplies and other pharmaceutical-related product manufacturing, the company ranks around eighth in the industry by revenue.
Through its corporate materials, the company has outlined diversification plans including expanding dialysis solution production capacity, upgrading real-time molecular diagnostic reagents, developing integrated point-of-care systems for blood glucose, HbA1c, and lipid measurement, and expanding into companion animal point-of-care diagnostics.
