Field tests I'd just like to point out that Sona's validation was carried out by MRI Global, a leading US lab that works with the Pentagon, US military, and FDA on a regular basis.
The field tests are not to "double check" some of the leading scientists and technicians. That part is done. They are to see how the test is carried out "in the field", to incorporate human error, level of experience needed to give test, how quickly layman pick it up, and how accurately it is executed by a "normal person", and not a trained technician at MRI Global.
The governing parties will be able to see how the test performs in a lab with trained technicians and how the test performs in a private setting with limited experience.
This will furthur be confirmation of Sona's professional approach to obtaining FDA EUA and HC approval.
