2 Product and Technology Innovation of Urinalysis in China
2.1 Overview
Urinalysis is the basic routine item of clinical laboratory, which is usually based on urine dry chemistry analysis and urine formed element analysis.
Urine dry chemistry analyzer generally uses reflectance photoelectric colorimetry to qualitatively or semi-quantitatively analyze the urine chemical composition of urine. In recent years, there are also instruments that use imaging colorimetry to do qualitative or semi-quantitative analysis. The feature of this method is that it can also provide the original image of the test strip for convenient review.
According to the technical principles, the urine formed element analyzers are mainly divided into static digital imaging shooting technology, flow digital image imaging technology, and flow nucleic acid fluorescence staining technology. At present, the main brands of urine formed element analyzers in the domestic market use flow digital imaging shooting technology or static digital imaging shooting technology. With the development of artificial intelligence technology, it plays an important role in laboratory medicine, especially in the automatic identification of cell morphology. The new generation of AI technology shows the characteristics of deep learning, autonomous learning, human-machine collaboration, and so on. All these technologies have been introduced into urine formed element analyzers. Through continuous training of massive image databases and autonomous deep learning, the automatic identification ability of intelligent equipment for urine formed elements has been continuously improved, and the burden of manual review has been gradually reduced, which takes digital image shooting technology in urine formed elements instruments to a higher level.
