Why did you and your wife spend/throw away $250 on a test of dubious validity (most yield questionable results; even the accurate ones still may not provide useful info) that will not be of any benefit to your health? Curiosity doesn't seem like a sufficient to get such a test.

IF someone insists on antibody testing for Covid 19, do yourself a favor and have testing done by labs that have an EUA (Emergency Use Authorization) for the FDA. Most tests do not have the EUA. None have been validated by the FDA. There's a lot a sham testing going on, as well. If you're going to get tested, research your Dr's test first. For those who are contemplating similar testing,

Cliff's Notes version:
"As important, those who use an antibody test need to understand its limitations and use test results as just one piece of data to inform decision making. All tests can provide at least some false results. Even a high-performing antibody test when used on individuals in a population that does not have many cases of COVID-19 infection – a population with low prevalence – may produce as many or more false results as true results because the likelihood of finding someone who has been infected is very small. This doesn’t mean the test is bad, but rather recognizes the inherent limitations of these kinds of tests. Therefore, it may be necessary for some individuals to have two serology tests performed to generate reliable results. That is why antibody tests should only be used as part of a well-conceived testing plan and why the results should always be interpreted by appropriate experts."
