According to statistics, about two-thirds of global medical decisions are made based on diagnostic information. Therefore, it is particularly important to further improve diagnostic techniques and means to provide more scientific decision-making for human disease prevention, diagnosis and treatment. In vitro diagnostic (IVD) will become one of the important development directions of medical industry in the future. In 2017, new technologies such as second generation gene sequencing and microfluidics, new models such as Internet +, big data and health management, and new medical precision targets have opened up a new world for the IVD industry and further enhanced the industry's development potential. Experts predict that by 2018 the global market for in-vitro diagnostics may reach 77.7 billion U.S. dollars.
