640,000 Virus Test Spain Bought from China Don’t Work: “They do not detect the positive cases as expected”March 26, 2020
The much-announced rapid tests for coronaviruses with which the Government wanted to start testing the broader layers of the population to find out what is the real size of the contagion in Spain do not work well. This has been confirmed by several microbiology laboratories of large hospitals in the analyzes that have been made of the kits recently arrived from China. The results of these preliminary tests are discouraging: “They do not detect the positive cases as expected,” says a source who has participated in the tests and who asks for anonymity.
The rapid tests, manufactured by the Chinese company Bioeasy, based in Shenzhen, one of the technological poles of the Asian country , have a sensitivity of 30%, when it should be higher than 80%, these sources indicate. One of the microbiologists who has analyzed the Chinese test assures: “With that value it does not make sense to use these tests.” The conclusion of the experts who have evaluated these detection kits is that they will have to continue using the current test, the PCR. This has been reported to the Carlos III Health Institute, under the Ministry of Health.
