MOSCOW, November 5 - RIA Novosti. The test systems for detecting coronavirus used in Russia correspond to the best world standards, said Sergey Avdeev, chief freelance pulmonologist of the Ministry of Health.
Earlier, he said that a test for coronavirus in about 30-40% of cases can show a false negative result, this is due to the collection of material, and not to the quality of the tests.
"The test systems used today in Russia for PCR testing for coronavirus are registered in the prescribed manner and correspond to the best world standards. PCR diagnostics of COVID-19 is the" gold standard "in most countries of the world, since it allows, if handled correctly, quickly and reliably to determine the presence of the causative agent on the nasopharyngeal mucosa, "said Avdeev, quoted by the press service of the Ministry of Health.
Errors in test results are detected in the inpatient unit, since patients are usually admitted to the hospital at later stages of the development of the disease, at which the probability of error is higher.
