Madrid, 27 Martha. Sensitivity tests for the coronavirus, acquired by the Spanish government in China, is 30%, and should exceed 80%. This is stated in the article of the Spanish socio-political newspaper El Pais. The authors refer to material sources in local laboratories.
"Rapid tests on coronaviruses, purchased in order to determine the real extent of the infection in Spain, does not work. This is confirmed by several microbiological laboratories, major hospitals in the analyzes, made from kits, recently arrived from China. The results are discouraging. They simply do not reveal positive cases ", - said the source, who participated in the tests and requested anonymity.
In turn, the Spanish Ministry of Health confirmed the poor results of the sensitivity analysis and the specificity. According to their initial plans, Over half a million of purchased tests were to provide mass screening of health care workers, as well as older people.
According to the source, Work rapid test is similar to the pregnancy tests: sample, taken from the patient's nose and throat, diluted and placed in the cartridge with the test strip, marked lines. When, if the tests reveal the presence of antigen, result is obtained through 10 or 15 minutes.
"Due to the low sensitivity of the material to the Government makes no sense to carry out mass Screening. It is simply impossible to determine, whether the test is true or false negative negative. That is, the patient may actually be infected, and the test will, that there is no ", - concluded the scientist.
At the moment, the world discovered more than half a million cases of coronavirus infection. recorded 24 215 deaths. Rospotrebnadzor reported, that under medical supervision in Russia remain 145 134 man. infected 845 human.
