Oh no Sorrento is not first for Covid19 testing !!
"The testing device, made by Abbott Laboratories and called BinaxNOW Ag Card.
Since April, Abbott has built two new facilities to manufacture BinaxNOW and plans to ship tens of millions of test in September, and scale up to producing 50 million tests each month by the beginning of October."
There is 7.8 billion people on Earth; If you test everybody 1 time it will take 13 years before Binax Now could provide for everyone a test. Therefore; In order to keep up with demand many different kinds of tests are needed to provide the testing requirements. There is plenty of market share for any company that can come up with a reliable test for the public.
