Sensitivity estimates—or how accurate a test is when COVID-19 antibodies are present— range from 88% to 100%. This means that for most tests, there is a less than five percent chance that a negative test result is wrong. However, a positive test result can have a higher chance of being false.

May 4: In a recent post, we warned readers against rushing out to purchase one of the many COVID-19 antibody tests suddenly flooding the market, noting that few of these tests have been independently validated, and many are grossly inaccurate. But what about the tests the U.S. Food and Drug Administration (FDA) has approved for emergency use?

It has always been a prime question of so many that how accurate is a covid antibody test. It has been seen in a study that IgG and IgM antibodies are having low sensitivity. As a matter of fact, the accuracy may vary.

An antibody blood test for covid-19, which the manufacturer Abbott claims is 99% accurate, has been certified for use by the European Union. The test—which has received its CE mark, meaning that it complies with EU safety rules—detects the antibody IgG to identify whether a person has had covid-19.

FDA has authorized antibody tests for this virus that have been submitted for their review. But these tests are not 100% accurate and some false positive results or false negative results may occur.

Antibody tests one week after first symptoms only detected 30% of people who had COVID-19. Accuracy increased in week 2 with 70% detected, and was highest in week 3 (more than 90% detected). Little evidence was available after week 3. Tests gave false positive results in 2% of those without COVID-19.

COVID-19 antibody testing, also known as serology testing, is a blood test that's done to find out if you've had a past infection with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19). An antibody test can't determine whether you're currently infected with the COVID-19 virus.
