In the future, detection of the new coronavirus will be faster and easier. The United States Food and Drug Administration yesterday approved the antigen test developed by California Quidel Corp. (9). It will only take 15 minutes to know if the tester is infected with the new coronavirus.
According to CBS News, Reuters and Politico, a US political news website. USA, The US Food and Drug Administration. USA (FDA) approved Quidel’s research and development in San Diego, California. Rapid Viral Antigen Detection Test, the draft FDA statement noted that this test method can quickly detect viral protein residues in the nasal cavity.
Quidel noted in the statement that the rapid detection method they developed can obtain the test results in 15 minutes.
The United States FDA is currently approving three new methods of detecting coronavirus. The first is the polymerase chain reaction (PCR) test, which is commonly known to the public. It is also commonly known as PCR nucleic acid detection. It is mainly used to detect nasal samples from subjects. Whether there is a viral gene fragment, this test method has high precision, the disadvantage is that it is quite time consuming, it can take several hours to get the result, and the cost of the test is high, usually only in a laboratory, hospital or university with professional team. Perform the inspection.
The second FDA-approved virus detection method is the antibody test (antibody test), which primarily detects the presence of antibodies in the test subject’s blood. Once the human body is infected, the body will induce an immune response to form antibodies against aliens. This detection method can help researchers understand how long the patient has been infected with the virus and the spread of the epidemic in the community. The downside is that it is impossible to determine the current infection of the patient. State.
Antigen testing does not require the genetic sequence of the virus to determine the subject’s current status of infection. The FDA said the cost of the antigen test is lower and that the test method is relatively simple. Eventually, it can detect millions of Americans every day.
