Да уж,
Что такое "multiplexed method" по твоему?

SARSeq can detect multiple respiratory viruses in a single reaction

Multiple infectious agents cause diseases with overlapping clinical symptoms to COVID-19, including influenza A and B virus, parainfluenza virus, rhinoviruses, and respiratory syncytial virus. It is expected that, particularly in the winter season, various respiratory symptoms will cause concerns and thereby dramatically increase the demand for SARS-CoV-2 tests. For SARSeq, adding amplicons corresponding to other infectious agents comes at little extra cost as long as it does not increase the required sequencing depth. Therefore, we can further multiplex SARSeq to detect other common respiratory viruses (or other pathogens) found in the same sample used for SARS-CoV-2 testing.

False. The CDC is not removing some PCR tests because they failed to differentiate between COVID-19 and Influenza. The agency says it is opting for multiplex assays (that can test for both viruses) to save time and resources.
