How should this message from the CDC be interpretted? Why is the CDC removing authorization for this test? This is the CDC post in question: https://www.cdc.gov/csels/dls/locs/2021/07-21-2021-lab-alert-Changes_CDC_RT-PCR_SARS-CoV-2_Testing_1.html https://www.cdc.gov/csels/dls/locs/2021/07-21-2021-lab-alert...

Here's a nice article answering your question and explaining the confusion here. It definitely seems like people who want to believe that covid is a hoax are taking this CDC post (which is technical and directed at scientists in testing labs) out of context and misinterpreting it to back up their narrative. https://www.factcheck.org/2021/07/scicheck-viral-posts-misrepresent-cdc-announcement-on-covid-19-pcr-test/ https://www.factcheck.org/2021/07/scicheck-viral-posts-misre... From the article: In explaining the CDC’s decision to end the use of its own PCR test at the end of 2021, Kristen Nordlund, an agency spokeswoman, in an email to us cited “the availability of commercial options for clinical diagnosis of SARS-CoV-2 infection, including multiplexed (discussed here) and high-throughput options” — referring to technologies that use an automated process to administer hundreds of tests per day. “Although the CDC 2019 Novel Coronavirus (2019 nCoV) Real-Time RT-PCR Diagnostic Panel met an important unmet need when it was developed and deployed and has not demonstrated any performance issues, the demand for this test has declined with the emergence of other higher-throughput and multiplexed assays,” Nordlund said. She continued: “CDC is encouraging public health laboratories (PHL) to adopt the CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay to enable continued surveillance for both influenza and SARS-CoV-2, which will save both time and resources for PHL.”

If I'm reading the post correctly (and I am no expert in the field), they're saying "this test will be obsolete by end of year, as better tests become available". It was an EULA, which is by intention "we wouldn't approve this so quickly except this is an emergency", so it's not surprising that as better tests were developed they would withdraw the EULA. Given that they were withdrawing it with several months' advance notice, I doubt there was anything massively wrong with it.

  I'm curious as to why there is no transparency from the CDC on why this test is being decommissioned. Just because there are tests that can do both Influenza and Covid, does not mean that this test would need to be retracted.
