RE:Selling all my sona today-Good luck to you but I think I will stick with SONA. You must be quite ill to have antibodies to any infection.... it can days with fever/malaise to generate an immune response with detectable antibodies. The Diasonic test is good but not much of an improvement on present testing. SONA's antigen test will detect much earlier, if it works as proposed, and detect virus particles possibly before the subject even shows or feels any symptoms. It would be a far superior test if it can get to market. Hopefully things will pan out...
