The rapid antigen tests, which hunt for proteins on the virus’ surface, give results in less than 30 minutes. They are less accurate than lab tests now in widespread use, which detect the virus’s genetic material and take hours to analyze. But a growing number of public health experts say trading off accuracy for speed is a gamble worth taking, as testing labs struggle to clear days-long backlogs.
Doug Bryant, president and CEO of test-maker Quidel, told investors last week that demand “will far exceed what all of the manufacturers in the rapid antigen space can produce, for at least the next several quarters.” States, which have spent months scrambling for protective equipment and testing supplies on the open market, are now competing for the rapid tests. A bipartisan group of seven governors said Tuesday that they would jointly purchase 3.5 million antigen tests from the only two companies now authorized to sell them — in the hopes of creating an incentive for test makers to ramp up production.
But even if the tests become more available, they’ll have to be deployed carefully, in ways that account for the increased risk of false negatives compared with tests analyzed in labs. The Centers for Medicare & Medicaid Services, which regulates nursing homes, acknowledges that antigen tests can’t be used to rule out coronavirus infection. But in a statement announcing the federal shipments, CMS Administrator Seema Verma said the tests were “one more tool in the toolbox” that could help nursing homes quickly identify infected residents and isolate them to halt the virus’ spread.
Testing is irrelevant in the south because its too slow and too many ppl are infected. Contact tracing is not possible. Shutdown or go Darwinian. Obviously China cares more about their people staying alive. Trump could careless. Bleach anyone?
Dear Media. They are not briefings. They are sucker punch to the media rallies where 45 gaslights and uses the media to dispense his lies.
