Abbott Laboratories said on Monday the U.S. Food and Drug Administration has issued an emergency use authorization for its lab-based COVID-19 antibody blood test.

The test, AdviseDx, can be used to identify a type of antibody called Immunoglobulin M (IgM) in blood samples to determine if someone has been exposure to the novel coronavirus, potentially indicating a recent or prior infection.

Abbott has already received emergency use authorization for seven tests, including molecular tests, a rapid antigen test and another test which can detect a type of antibody called IgG.

The FDA's emergency use authorization allows the use of unapproved medical products in an emergency to diagnose, treat, or prevent serious or life-threatening diseases with no adequate or approved alternatives.

IgG is longer lasting in the body after an infection, but IgM is more useful for determining a recent exposure to the coronavirus as these antibodies become undetectable weeks to months following an infection, Abbott said http://newsfile.refinitiv.com/getnewsfile/v1/story?guid=urn:newsml:reuters.com:20201012:nPn8KFxtXa.

Unlike molecular tests, which can detect whether someone has the coronavirus, antibody tests determine if someone has had a previous infection by detecting disease-fighting proteins called antibodies.

However, antibody tests are not recommended as the sole basis of diagnosis of COVID-19 as these antibodies may not be detected in the early days of the infection.
