"New tests typically require validation — running the test on known positive samples from a patient or a copy of the virus genome. The F.D.A.’s process called for five. Obtaining such samples has been hard because most hospital labs have not seen coronavirus cases yet, said Dr. Karen Kaul, chair of the department of pathology and laboratory medicine at NorthShore University HealthSystem in Illinois."
"The C.D.C. had designed its own test as it typically does during an outbreak. Several other countries also developed their own tests.
But when the C.D.C. shipped test kits to public labs across the country, some local health officials began reporting that the test was producing invalid results."
How could they know they were producing invalid results?
