China for Yu body outside diagnosis technology of needs is towards Poles of development: a is to efficient of instrument equipment, and module type of combination and line type of automation control of height integrated, and automation of instrument diagnosis technology, greatly improve diagnosis detection of efficiency; another a is simple, and fast easy universal and site detection of diagnosis technology, requirements not by instrument limit, and operation simple of, and results report timely accurate of, increasingly by clinical medical personnel of favored. Hospital needs is also polarized: high-end hospitals require high throughput, high efficiency, high sensitivity detection products, while grass-roots hospitals need fast, affordable, secure and efficient products. And research shows that early clinical chemistry diagnostic in vitro diagnostic industry market share, but in recent years more than clinical chemistry immunoassay has gradually share of diagnosis, and colloidal gold assay test paper as a newly developed technology, the fastest-growing of all diagnosis types. The class test is not only suitable for fast checking of large hospitals, also suitable for family planning service stations, community clinics and home. At present, early pregnancy tests and ovulation test strips has been used in the home, but other products have not entered the home.
