Scientists examine the polymerase chain reaction (PCR) and test reliable tools for diagnosing COVID-19. However, social media posts misrepresent the recent Centers for Disease Control and Prevention announcement and falsely claim that the government admits that PCR tests are unreliable.
In the early days of the COVID-19 pandemic, the Centers for Disease Control and Prevention Development and deployment Proprietary polymerase chain reaction, or PCR, Tests to identify infections with the new coronavirus (but First deployment I was suffering from some problems).
A year and a half later, at the end of 2021, a federal agency notified the Institute that it would withdraw the emergency use authorization request for the study from the Food and Drug Administration and thereby discontinue use.
Agency July 21 notification The lab recommends using “one of the many FDA-approved alternatives” and considers adopting a multiplexing technique that facilitates the detection and identification of SARS-CoV-2 and influenza virus. I encourage you to do that. “like that Multiplex test, include One from CDCCan search for both new coronaviruses and multiple types of influenza at the same time. This saves testing material and allows the Institute of Public Health to monitor influenza during testing for the virus that causes SARS-CoV-2 or COVID-19.
However, the CDC does not state that it no longer supports the use of common PCR tests. Approved By the FDA — or it SARS-CoV-2 proprietary PCR test The difference between coronavirus and flu cannot be distinguished because the virus posts that are spreading online are falsely claimed.
“After 180 million positive cases, the CDC issued a statement withdrawal from detecting Covid using PCR tests due to lack of detection to distinguish Covid from influenza. Read a screenshot of the July 25 tweet Post On Instagram. The post received over 4,000 likes.
Similarly, a Facebook post on July 26th Claim: “Big News-CDC withdrew PCR test from FDA EUA. The main reason was the inability to distinguish between Covid and influenza.”
The CDC PCR test in question only searches for SARS-CoV-2, not influenza. This is quite different from the test that falsely diagnoses a case of influenza as COVID-19, as the post falsely suggests.
Tweets deleted from “UK Medical Freedom” on July 23 False claim “The FDA today announced that the CDCPCR test for COVID-19 has failed a complete review. The emergency use authorization has been revoked.”
July 25, two days later, Controversial gym owner Ian Smith, New Jersey, Viral Tweet “The FDA has confirmed that the PCR tests for testing COVID are inaccurate.” He called COVID-19 a “manufactured crisis.”
As we said, the announcement of the issue was from the CDC and was about plans for the final discontinuation of its own tests. It is still in use. An FDA spokesman confirmed that the FDA did not revoke the emergency use authorization for the CDC test or question the reliability of the PCR test.
In explaining the CDC’s decision to end the use of its own PCR test at the end of 2021, government spokeswoman Kristen Nordlund said, “Commercial options available for clinical diagnosis of SARS-CoV-2 infection. I quoted “sex”.Including multiplexing (discussion here) And High Throughput Options ”—See technology Manage hundreds of tests per day using an automated process.
“The CDC 2019 Novel Coronavirus (2019 nCoV) Real-Time RT-PCR Diagnostic Panel met significant unmet needs when developed and deployed and did not show performance issues, but the demand for this test was Higher throughput, multiplexed assays that have been reduced by other emergences, “says Nordlund.
She goes on to say: “CDC has decided to employ the CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay to enable continuous monitoring of both influenza and SARS-CoV-2 at the Institute of Public Health (PHL). ) Is encouraged. For PHL. “
FDA website list Numerous PCR tests for COVID-19 for which an emergency use authorization has been issued.
Jim McKinney, an FDA spokesman, said in an email so far: “The FDA has approved over 380 tests and sample collection kits to diagnose COVID-19, many of which are PCR tests. PCR tests are generally referred to as the” gold standard “for COVID-19 diagnosis. It is considered. “
“The FDA has not issued a statement that doubts the reliability of general PCR test results and will continue to consider permitting validated PCR tests,” he added.
Dr. Michael MinaHarvard University’s assistant professor of epidemiology said the CDC’s decision on the test made sense given how the landscape changed.
“CDCs may get their own EUA for testing, because hundreds of other laboratories have their own EUA and many companies have EUA for manufacturing testing. , Because the CDC no longer has to use its own tests, “he said in an email. .. “Every major company, such as Roche, Horizon, and Abbott, has their own test kits and equipment. Second, Thermo Fishers around the world has an EUA for PCR kits that can be performed in exactly the same way as the CDC assay. Therefore, there is really no reason for the CDC to hold the EUA. “
Mina said the move should be done with caution, as some public health laboratories may currently rely on CDC testing.
“After all, the CDC EUA was more or less a recipe for how to test CoVID and some ingredients,” Mina said. “Now we have all these kits and a fully automated process, so we don’t need them anymore.”
