New coronavirus antigen test with fast results approved by FDA
PROVIDENCE, R.I. (WLNE) – Regulators in the U.S. have approved a coronavirus test that administration officials have deemed vital to opening the country.
On Saturday, the Food and Drug Administration (FDA), announced emergency authorization for antigen tests.
The antigen tests were developed by Quidel Corp. of San Diego, C.A.
The FDA said in a statement that this test can rapidly detect fragments of virus proteins in samples collected by swab swipes inside the nasal cavity.
The antigen test is the third type of test to be approved by the FDA.
The only way to diagnose active COVID-19 particles is to test a patient through a nasal swab.
Testing this way is considered highly accurate, although the tests can take hours, can be costly and specialized equipment found at commercial labs are needed for these tests.
Another type of test looks in the blood for antibodies. This tests looks for proteins produced by the body days or weeks after fighting an infection.
This type of a test is helpful for researchers in understanding how far a disease has spread within a community. This test is not useful for diagnosing an active infection.
The antigen test can diagnose active infections. The test does so by detecting the earliest toxic traces of the virus rather than the genetic code of the virus itself.
