Widespread Criticism of U.S. PCR COVID Testing

12/14/2020

The outgoing Administration has consistently quoted the "successful" implementation of millions of COVID-19 PCR assays.  Bill Gates, entrepreneur, philanthropist and founder of Microsoft regards the testing component of COVID-19 control in the U.S. as ineffective and a waste of money. The entire U.S. program of testing based on PCR assay has been ineffective and the contribution of this aspect of control contrasts poorly with the success of the Warp Speed development of vaccines.

 

 The contribution of ‘testing’ in reducing the incidence rate of COVID-19, depends on identifying both asymptomatic and affected individuals and having them isolate to prevent dissemination of virus.  Any delay greater than 48 hours in receiving results invalidates the Purpose of testing individuals.

 

Dr. Brett Giroir, Assistant Secretary for Health responsible for the inadequately implemented and fragmented testing program effectively agreed with Gates in a recent interview on CNN. Dr. Giroir stated, "we are never going to be happy with testing until we get turnaround times within 24 hours and I would be happy with point-of-care testing everywhere".  Giroir added that more than half of COVID testing is conducted at central laboratories with turnaround times of over four days.  The highest daily test rate was on July 28th with 733,000 tests conducted, most of which fell into the "useless" category with respect to prasctical control of the infection.

 

A number of prominent epidemiologists have noted that a lateral-flow immunoassay test similar to a pregnancy test kit with about 90 percent sensitivity and 95 percent specificity, costing in the region of $1 to $3 would be more beneficial than PCR procedures at $100 offering 99 percent sensitivity but with extended delays in obtaining results.

 

Early in the COVID outbreak, the question of testing was politicized.  Prominent members of the outgoing Administration believed that the rapidly ascending incidence rate actually attributed to widespread community infection was in fact due to "testing".  A wide gulf in understanding developed between epidemiologists affiliated with the NIH and the Centers for Disease Control and Prevention (CDC) with the non-scientists in the White House concerned with optics of ascending incidence rates. Overt attempts were made to suppress statistics on new cases and hospitalizations to support the myth that the nation had somehow “turned a corner” to permit restoration of pre-COVID activities.  The role of the CDC with respect to testing was subject to restraints imposed by the Administration leading to what may be regarded as a national failure with respect to a critical aspect of control. China, Taiwan, South Korea and New Zealand achieved early and rapid control of COVID through testing and quarantine and implementation of commonsense protective measures.

 

To implement effective prevention of COVID-19 in the context of packing plants and food production facilities antigen tests applying lateral immunoflow technology are required.  These provide low-cost and almost instant results that can form the basis of a logical assignment of employees to either quarantine or their workplace.
