On February 14, 2020, the State Key Laboratory of Respiratory Diseases said that under the guidance of Academician Zhong Nanshan, the laboratory had jointly developed a rapid detection kit for IgM antibody in novel coronavirus, and the preliminary laboratory and clinical evaluation had been completed.

According to reports, only one drop of blood is needed to get the test result within 15 minutes, and the patient's plasma can still be tested after being diluted 500 to 1000 times. The State Key Laboratory of Respiratory Diseases said that the kit was tested in a hospital in Hubei.

By rechecking the blood samples of some patients who were clinically diagnosed as positive for novel coronavirus infection (but negative for PCR nucleic acid detection), the kit can detect a considerable number of (IgM) positives, indicating that it can supplement the nucleic acid detection.

Samples of this kit (for scientific research) have been sent to grassroots health institutions in Wuhan, Huanggang, daye city and other places in Hubei Province, and used together with nucleic acid detection and other technologies to detect and evaluate novel coronavirus infection.

Unprofessional operation may lead to different results.

It is worth noting that the whole blood sampling detection process seems simple, and the time consumption does not exceed 1 minute. However, disinfection, needle insertion, hemostasis and other processes still need professional operation methods, and the operators in the video wear standardized protective equipment, and the overall testing environment is clean and hygienic, which makes people doubt the saying that "they can operate at home".

Xu, vice president of Guangdong Medical Device Industry Association and a member of the expert group, said in an interview with reporters on February 2 1 that according to the regulations, the test kits currently on the market cannot be tested outside medical institutions. "Personal operation technology is unprofessional, and it is prone to danger during blood collection, and the test results may also be biased."
