China Economic Herald, China Development Net News reporter Miao Xiaoqin reported from Shanghai On the opening day of the 73rd World Health Assembly on May 18, good news came from Japan that the accuracy rate of the new coronavirus antibody detection kit was made in China. Not long ago, the Ministry of Health of Malaysia also released a similar evaluation news, and the antibody detection kit developed in China was the first to be tested for return to work. This has put the positive label of "high-quality products made in China" on antibody detection kits around the world.

Japan: The accuracy of antibody testing is very close to nucleic acid testing

As the first hospital set up by the Japanese government to treat patients with new coronary pneumonia, Sagamihara Collaborative Hospital announced on May 18 the results of a comparative study of several new coronavirus antibody detection kits in China, South Korea and other countries. Biomedical Technology Co., Ltd.'s 2019-nCoV IgM/IgG antibody detection kit ranked first in accuracy, with an excellent score.

According to the director of Sagamihara Collaborative Hospital, Zhikazu Jing, because the academic community has always been in doubt about the accuracy of the new coronavirus antibody detection, the hospital has analyzed and studied 10 antibody detection kits through lateral flow immunochromatography (LFIA). , and the kappa coefficient was used to evaluate the consistency of antibody detection and nucleic acid detection. The result of the evaluation is that the antibody detection kit of China Shanghai Liangrun Biomedical Technology Co., Ltd. occupies the top position, the sensitivity of 69 samples is 95.5%, the specificity is 97.8%, the kappa coefficient compared with nucleic acid detection is 0.93, the rating for excellent. The average k coefficient of the other 9 companies is 0.64±0.03, and the rating is good.

Malaysia: Return to work after two negative results

Not long ago, the Ministry of Health (MOH) of Malaysia made a recommendation to the Social Security Organisation (Socso) on the screening of COVID-19 for returning workers, given that the cost of nucleic acid testing is about RM400 to RM700, and it takes 24 It takes 48 hours to produce results in the laboratory, so a cost-effective antibody test that can quickly produce results is recommended, and the Ministry of Health has announced the evaluation list of antibody kits. Coincidentally, the highest accuracy rate is still the antibody detection kit developed by China Shanghai Liangrun Biomedical Technology Co., Ltd.

Dr. Noor Hisham Abdullah, Minister of Health of Malaysia, said that for the new coronavirus screening of returning workers, it is recommended to use antibody testing, but it needs to be done twice to confirm. Must be retested on the seventh day from the first test. If it is negative again, it can be diagnosed as uninfected and can return to work. If the antibody test is positive, the person must be tested for nucleic acid by nasopharyngeal swab again.

In his speech at the opening ceremony of the video conference of the 73rd World Health Assembly, President Xi Jinping said that China has effectively reversed the situation of the epidemic, shared its experience in prevention, control and treatment with all parties without reservation, and has done its best to provide assistance to countries in need. Lots of support and help. China not only released the virus gene sequence and other information at the first time, but also provided high-quality epidemic prevention materials to the world, so as to unite and cooperate to overcome the epidemic and jointly build a community of human health.
