On May 13, Japan’s Ministry of Health, Labour and Welfare approved an anti-body test that can detect the novel coronaviruses in 30 minutes, NHK reported. Japan’s Ministry of Health, Labour and Welfare has reportedly approved the use of antigen testing kits, and will give guidance on testing methods and the scope of subjects. Anti-body detection is a simple detection method that can detect whether or not to be infected with the new coronavirus, about 30 minutes can determine the results.
The report said the test was like a flu test, taking samples from deep in the subject’s nasal cavity and dropping the liquid containing the sample on the reagent to confirm that a line-out strip would emerge.
However, because of the risk of infection when doctors are tested, antigen testing is limited to medical institutions that have been tested for nucleic acid and have taken adequate precautions against infection, and are not widely available in ordinary clinics. Antigen testing will be mainly carried out in medical institutions in Tokyo, Kanagawa, Osaka, Hokkaido and other areas with more serious outbreaks.
In addition, compared with nucleic acid testing, anti-body test accuracy is low, infected people may not test positive, at this time, will also fight the original test negative test to implement nucleic acid testing.
