Well technically they are all new tests, but was it not already being used by many other countries and already had approval in the US when we decided to use it?
Approved because of a relaxing of regulations. Approved doesn't mean as much right now. Just look at how the market is being flooded with bad antibody tests. The fact is Utah has shown these tests look like they are producing a lot of false negatives.
The state lab is testing the effectiveness of the machines the tests run through and not the actual accuracy of the tests as far as I know.
