The Russian covid-19 test is 1/16 as sensitive. Let’s hope these soldiers won’t touch off a fresh wave of infections in Italy. It’s the last thing they need right now.
According to PCR News, the Russian test is based on the same method used by other countries.
But the Russian test, PCR News wrote, only detects the virus when there are over 100,000 copies of it per milliliter in a sample. That is far more than in other countries tests. A test in use in the U.S., for example, will pick up the virus with just 6,250 copies.
That would mean its about 10-16 times less sensitive than whats available in the U.S., Carmen Wiley, president of the American Association of Clinical Chemistry, told ABC News by a phone. At such a level, she said there was a risk the Russians were missing cases, in particular where people were asymptomatic. ]

"Effective immediately, people in Sacramento County should not quarantine themselves if they've been exposed to the COVID-19. Instead, they should go into isolation only if they begin to show symptoms of the respiratory virus, the county's health department says."
"The decision of what steps to implement will be local," Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, said last week. She added, "CDC's role is to provide technical advice to states and counties."

"The Russian government is aware of the issue and is preparing to launch a second test to act as a control for the first, Kurinny, the lawmaker, told ABC News. He said he was also worried Russia is only testing a "very narrow" group, confined largely to those arriving from countries deemed as hotspots for the virus and who show symptoms."
