US approves new coronavirus antigen test with fast results

Two other types of tests for the coronavirus have received the emergency authorization.

The FDA said that it expects to authorize more antigen tests in the future. Positive results are "highly accurate", but a negative result does not necessarily rule out the presence of the virus.

Once these antigen tests are put into the market they can potentially test millions of Americans per day, "helping our country better identify infection rates closer to real time" the FDA said.

The Food and Drug Administration on Friday authorized a new coronavirus antigen test produced by Quidel Corporation, a California-based diagnostic testing company.

The tests work by detecting fragments of proteins on or within the virus via samples swabbed from the nasal cavity.

The Sofia 2 instrument also offers 2 distinct workflows: depending upon the user's choice, the Sofia 2 SARS Antigen FIA cartridge is placed inside Sofia 2 for automatically timed development (WALK AWAY Mode); or test cartridges can be placed on the counter or bench top for a manually timed development and then placed into Sofia 2 to be scanned (READ NOW Mode), allowing the user to markedly increase testing throughput per hour. Broader testing is generally agreed to be a priority before the economy can be safely reopened. She said that health-care officials and providers were simply unable to achieve that kind of scale with the PCR test.

The Ministry would like to report that today, 1150 rapid screening tests and 333 PCR tests were done in the public sector.

The new test might be useful for testing patients requiring immediate medical attention as well as those getting ready to undergo operations, he said.

But, he added, that accessibility also hinges on an individual doctor's willingness to open their office to potential viral exposure. In some cases, patients have to wait for a week to learn the outcome.

"Inadequate tests may miss patients with active infection or falsely categorize patients as having the disease when they do not, further hampering disease control efforts", World Health Organization officials said. "We need to reinforce that".
