Immunoassay is a highly selective bioanalytical method that measures the presence or concentration of analytes ranging from small molecules to macromolecules in a solution through the use of an antibody/antigen immunoassay test as a biorecognition agent.

Immunoassays (IAs) play a critical role in various bioanalytical settings, such as clinical diagnostics, biopharmaceutical analysis, environmental monitoring, security, and food testing. It is even more critical to effectively diagnose, monitor, and manage the patients' health. Considering the prominent role that IAs play in clinical decision-making, they are indispensable for healthcare settings.

As one of immunoassay analyzer manufacturers, Genrui keeps branding its own IAs platform, which is called specific protein analysis solution, the PA series including its instrument and reagents. After nearly 20 years of effort, the platform has become one of the most well-known analysts in the field in domestic and foreign markets. Now it is the Top 1 specific protein solution export in China.

All PA analyzers of Genrui use the nephelometry method to improve accuracy, repeatability, and reduce carryover. These analyzers include fully-auto one PA120 and semi-auto Genrui PA54. The former basically cover all demands from a small to the medium laboratory, with its high throughput and high automation. The latter shows the huge market capacity for some countries and regions under development and construction because of its compact model and good performance. The most important is the PA-compatible reagents that Genrui provides, which really play an irreplaceable part in the diagnosis of diabetes, infection, renal disease, rheumatoid disease, immunological diseases, clotting disorders, etc.
