Academician Zhong Nanshan directed the development of a rapid detection kit, and the results can be obtained within 15 minutes after taking a drop of blood.

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

  According to reports, only a drop of blood can be taken to obtain the test results within 15 minutes, and the patient’s plasma can still detect positive bands after being diluted 500 to 1000 times. Compared with RT-PCR nucleic acid detection currently used for diagnosis, this kit is simpler and more efficient, with high sensitivity and specificity. It can effectively break through the limitations of the existing detection technology on people and places, shorten the detection time, realize rapid diagnosis of suspected patients and on-site screening of people in close contact, and promote the forward and downward movement of diagnostic screening.

  △ The blood sample of an infected person in novel coronavirus from left to right can still be detected by this kit after being diluted to 1:512 times.

  The State Key Laboratory of Respiratory Diseases said that the kit was tested in a hospital in Hubei. By reexamining the blood samples of some patients who have been clinically diagnosed as positive for novel coronavirus infection (but negative for PCR nucleic acid detection), the kit can detect quite a few (IgM) positive, suggesting that it can complement the nucleic acid detection. At the same time, in the detection test of more than 600 clinical samples from Hubei and Guangzhou, the positive detection rate of (IgM) in the kit has a high coincidence rate with the clinical diagnosis results.

  According to reports, at present, a large number of samples of the kit (for scientific research) have been sent to grassroots health institutions in Wuhan, Huanggang, daye city and other places in Hubei Province, and used in the test and evaluation of novel coronavirus infection together with nucleic acid detection and other technologies.
