Scientists may have developed a new blood test that would help determine the severity of your COVID-19 symptoms.

The news: Scientists at George Washington University said they developed a new tool — deemed as a “simple blood test” — that “can quickly detect if someone has COVID-19 and predict how severely their immune system will react to the infection,” according to NBC Washington.

  • “We’re using the person’s own body to tell us that they think something is awry,” said Dr. Tim McCaffrey, lead researcher for the project.
  • The researchers published their findings of the blood test in the medical journal Public Library of Science (PLOS ONE).
