COVID-19 Family Antibody Testing Products not Meet Standards
According to the Fox News website, the US FDA Commissioner
and several public health laboratory officials have warned that the vast
majority of COVID-19 blood antibody test products do not meet the standards.
Blood antibody test is different from the nucleic acid test
Eric Blank, a spokesman for the American Association of
Public Health Laboratories, pointed out that the blood antibody test is
different from the nucleic acid test of nasopharyngeal swabs currently widely
carried out. It can identify viral antibodies in the blood. Diagnosis of
various infectious diseases. In order to urgently respond to the US COVID-19
epidemic, the FDA has abandoned the initial review of blood test products.
At
present, there are more than 70 companies selling so-called antibody detection
products, the accuracy of which is in doubt, and no one knows which one is
accurate.
Wild West Show
Blank said that this is like a "Wild West Show",
which has caused huge confusion in disease prevention and control and will take
some time to deal with.
US FDA Director Stephen Hahn pointed out that some companies
have false propaganda. They claim that their blood test products are approved
by the FDA and can be used to diagnose COVID-19.
At present, FDA has approved
only one blood test product for clinical laboratories, so these products
involve false marketing, and FDA will take action against these product
companies.
Dr. Allison Rakeman of the New York City Public Health
Laboratory said that medical experts currently have no consensus on the
proportion of asymptomatic carriers of COVID-19, and the estimated range is
between 25% and 50%.
Wrong test results have made people less vigilant,
thinking that they have been immunized or no longer spread the virus, and then
they come in direct contact with the elderly from the outside-we do not want to
create a false sense of security.
Officials in Laredo, Texas, reported this month that
suspected patients can be tested at the local drop-off test point-they can drive
to the test station by themselves, and they can be tested by medical staff
without getting off the car. However, the 2,500 antibody detection products set
up at these monitoring points are fraudulent. Government officials spot-checked
the "FDA approved COVID-19 rapid test product" ordered by a local
clinic, and its accuracy is far below the promised standard.
Deborah Birx, coordinator of the White House Coronavirus Task
Force in the United States, pointed out in a recent press conference that the
government will inform a test that is reliable for all Americans. If you see
other products online, please do not buy them.
While the US official issued warnings about various test
products, the reagent company also raised its own doubts. Dr. Stephen McColgan,
chief medical officer of California-based Vivera Pharmaceuticals, said that the
company's rapid antibody test submission has been three weeks ago, and the
product has not been approved due to a large number of "red tape"
processes.
