The U.S. Army discovered the blood test, showing if you're infected with coronavirus within 24 hours.

In what may be significant progress, project co-ordinators hope that the blood-based test will be able to detect the presence of the virus as soon as possible within the 24-hour time span after infection.

This will happen before people show symptoms and days before a transporter is considered capable of spreading it to other people.

This test works about four days before actual tests can detect the virus.

The Guardian writes that the test has emerged from a project created by the Advanced American Army Protection Research Agency (Darpa), aimed at quick diagnosis of poisons from germs or viruses or chemicals.

The new test is expected to be presented for approval of emergency use (EUA) from the US Food and Bars Administration (FDA) within a week.

“The concept fills a diagnostic gap worldwide,” told Guardian the head of the Darpa Biological Technology Office, Dr Brad Ringeisen.

The purpose of the research is to develop and prove an early diagnostic test of the blood response for Ovidius,” said Prof. Stuart Sealfon, who leads the research team at Mount Sinai Hospital in New York.
