I agree with your reply. Thank you for it. The recent seroprevalence study performed in Santa Clara County [0] [1] used an immunoassay manufactured by Premier BioTech, Minneapolis, MN. Their page entitled "PCR And Serology Based Testing Explained" does a very good job explaining what we both understand [2]. I stand by my opinion that it is unrealistic to use RT-PCR testing on the entire U.S. population. It is too sensitive and too time-consuming given the time constraints we are under. This Wash Post article (printed by MSN) describes why the CDC had to recall its initial testing kits.
