Without media noticing it, the Centers for Disease Control and Prevention (CDC), the national public health agency of the United States, has stopped the use of the Real Time-Polymerase Chain Reaction (RT-PCR) test to detect Covid-19.
The reason implied that the test could no longer distinguish Covid-19 and ordinary influenza (flu).
In a memo dated 21 July 2021 on its website cdc.gov from its Division of Laboratory Systems, addressed to “Individuals Performing COVID-19 Testing” and classified as “Lab Alert,” the CDC said:
“After December 31, 2021, CDC will withdraw the request to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel, the assay (test) first introduced in February 2020 for detection of SARS-CoV-2 only.
“CDC encourages laboratories to consider adoption of a multiplexed method that can facilitate detection and differentiation of SARS-CoV-2 and influenza viruses.”
In the Philippines, the RT-PCR is the most expensive Covid test and which Health Secretary Francisco Duque III once dubbed “the gold standard” in detecting Covid-19.
