I believe PMED and SONA have used the same marketing / promotion firm. They both have products that were supposed to test for Covid-19. PMED is also seeking the ability to use AI to test for other things also but still no success that I am aware of.
If PMED continues to provide no proof that the AI testing works... PMED could end up like SONA IMHO. Maybe even worse
All my opinion only
