“In low prevalence populations, the result of a single antibody test is not likely to be sufficiently accurate to make an informed decision regarding whether or not an individual has had a prior infection or truly has antibodies to the virus. A second test, typically one assessing for the presence of antibodies to a different viral protein, generally would be needed to increase the accuracy of the overall testing results.”

“If you have a positive test result on a SARS-CoV-2 antibody test, it is possible that you have recently or previously had COVID-19. There is also a chance that the positive result is wrong, known as a false positive. False positive tests may occur:

“Because antibody tests may detect coronaviruses other than SARS-CoV-2, such as those that cause the common cold.

“When testing is done in a population without many cases of COVID-19 infections. These types of tests work best in populations with higher rates of infection.”

I trust the IRS more than the FDA or CDC these days.
