Antibody tests

From Abbott... I think they make the test equipment...

ARE COVID-19 ANTIBODY TESTS ACCURATE? The Abbott antibody test detects antibodies to the virus that causes COVID-19. In medical and scientific language, the Abbott antibody test has 99.63% specificity and 100% sensitivity at the time of detecting antibodies 14 days or greater, post symptom onset. This means that 14 days after the onset of symptoms, the test will identify an individual who has developed antibodies to the COVID-19 virus (SARS-CoV-2) 100 % of the time. This is called the sensitivity of the test. This means that if you have developed antibodies to the COVID-19 virus the Abbott test is able to detect them. The Abbott test also tells you that the antibodies the test detected are antibodies to the COVID-19 virus 99.63% of the time. This is called the specificity of the test. This means that if you have an Abbott test for antibodies to the COVID-19 virus that detected antibodies, there is great certainty that these antibodies are to the COVID-19 virus and there is almost no possibility that the antibodies the test detected developed in response to another virus that you were previously exposed to.

Knowing if you have COVID-19 antibodies can benefit not just you, but everyone.
