Chinese Made Covid19 Test Are Failing

Microbiology experts in Spain have said that rapid coronavirus tests that the country bought from China are not consistently detecting positive cases.

The error was discovered as Spain is in the grip of one of the worst coronavirus outbreaks in the world, second only to Italy in the number of reported deaths.

Studies on the tests done in Spain found that they had only 30% sensitivity, meaning they correctly identify people with the virus only 30% of the time, sources told the Spanish newspaper El País.

Those sources told the newspaper that the tests should have a sensitivity of more than 80%. The US Centers for Disease Control and Prevention says rapid tests for influenza are required to have 80% sensitivity.

Rapid tests can get a result in minutes but are generally less accurate than other tests. Numerous companies around the world are producing them.

The studies prompted the Spanish Society of Infectious Diseases and Clinical Microbiology to formally recommend not using these tests, El País reported. Health workers are now meant to use other tests that take longer to give a result.

Fernando Simón, the director of Spain’s health-emergencies coordination center, said on Thursday that Spain checked 9,000 of the tests, found that their results were not consistent enough, and decided to return them.

Spain’s health ministry confirmed the results of the studies into the tests to El País, with a spokesman saying the Carlos III Health Institute, a public-health institute that reports to the government, “detected a sensitivity that does not correspond to what is established in the technical sheet.”

The spokesman said that the institute had recalled a shipment of the tests sent to Madrid. New tests approved by the government will be rolled out instead, he said.

The tests were being used in the regions of Andalusia and Galicia, and they were first used in the Madrid region on Wednesday.
