By James Alexander, Yiling WangICHONGQING|Jun 16,2020

Chongqing- Keysmile Biological Technology Ltd is a high tech company based in the Chongqing Liangjiang New Zone. As the need for COVID-19 screening equipment continues to grow in the interests of epidemic prevention and control, the production of their automatic chemiluminescence immunoassay analyzer(CLIA) machine has increased four-fold in order to meet demand, a smart solution for COVID-19 Tests.

An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody or antigen. (Source; Wikipedia.org)

The analyzer tests patients for COVID-19 using chemiluminescence technology to detect the concentration of anti-bodies. Results not only produce a positive or negative diagnosis, but can also assess the level of susceptibility, and whether a patient has contracted certain viral infections in the past.

Vice general manager Shawn Hu explained how the machine works, its unique features, and the contribution it is making to epidemic prevention and control internationally during the interview.

Later, we toured inside the testing facility to see examples of finished products, the inner structure, and even a demonstration of the analyzer equipment in action.

On the day of our visit, there happened to be two foreign nationality Chinese engineers present who were undergoing a month of training in how to operate the machine, with the purpose of teaching others when they return to France and Germany. 

The engineers Mr. Lu Xuejun and Mr. Zhu Junyong kindly agreed to answer questions on camera and describe their experiences to date.
