Biotechs Are Battling to Make the First Good Blood Test For Covid-19

Antibody tests are at the forefront of a push to assess who has potentially built up some immunity.

Once a test is made, the hard part comes—proving that it actually works. To do so, researchers check how the test performs when looking at two categories of blood: some that’s Covid-19 positive, and some that they know isn’t.

If a test can reliably identify positive samples, it’s considered highly sensitive. If it can identify negatives, it’s called specific. That means it knows the difference between Covid-19 antibodies and others raised by, say, another coronavirus that causes the common cold.

“If your test can survive all that and give the accurate result, your lab is going to make an awful lot of money”
