From the Ted Talk by Cella Wright: How do you know if you have a virus?

Unscramble the Blue Letters


Before the immunoassay, haelth professionals draw blood from an individual. This sample then comes into contact with a portion of the virus of interest. If the body has, in fact, been exposed to the vrius in the past, the body’s virus-specific aiedbnoits will bind to it during the test. This reaction pdrcoeus a change in color, indicating that the sample tested positive and that the individual has been exposed to the virus.

Immunoassays are especially ipnoramtt when it comes to retroactively diagnosing people who were infected but went unettesd. And there’s exciting potential for those who have developed immunity to a virus: in some csaes, their blood plasma could be used as treatment in people who are currently fighting it.

Original Text


Before the immunoassay, health professionals draw blood from an individual. This sample then comes into contact with a portion of the virus of interest. If the body has, in fact, been exposed to the virus in the past, the body’s virus-specific antibodies will bind to it during the test. This reaction produces a change in color, indicating that the sample tested positive and that the individual has been exposed to the virus.

Immunoassays are especially important when it comes to retroactively diagnosing people who were infected but went untested. And there’s exciting potential for those who have developed immunity to a virus: in some cases, their blood plasma could be used as treatment in people who are currently fighting it.
