Spain, the Europe's second worst-hit country claims coronavirus tests it bought from China are not working

In Spain, microbiology experts have claimed that rapid coronavirus tests that the country bought recently from China are not detecting all positive cases.
The issue was detected as Spain is in the grip of one of the worst coronavirus outbreaks in the world, just after Italy, USA and China in the number of reported cases.
Studies on the tests done in Spain found that they had only 30% sensitivity, this means that 70% of the time cases are not correctly identified. Meanwhile rapid tests are required to have a 80% sensitivity to be used.
These rapid tests can get a result in minutes but are generally less accurate than other tests conducted in the health centers. Numerous companies around the world are producing them taking advantage of the global demand.
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.
The director of Spain's health-emergencies coordination center, mentionned 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."
According to the spokeman, the institute has now recalled a shipment of the tests sent to Madrid. New tests approved by the government will be rolled out instead.
The tests were being used in  regions like Andalusia and Galicia, and they were first used in the Madrid region on Wednesday.
Delays from implementing the new test will further harm Spain's efforts to contain the virus, which had killed over 4,000 people in the country as of early Thursday.
