Antibody tests unreliable: CDC

The CDC has released new guidance on antibody tests, warning that they can be wrong half the time and shouldn't be used to inform important policy decisions.

The antibody test, also known as a serologic test, is a blood test that checks the body to see if it has antibodies that can fight COVID-19, and can help people figure out if they had COVID-19 and recovered.

The immune system creates antibodies to fight disease, and often these antibodies remain in the body after recovery, and can be donated to people currently fighting coronavirus.

But this medical test is often inaccurate. Sometimes the test can result in a false positive, wrongly suggesting a patient does have coronavirus-fighting antibodies, or a false negative.
