How do you know you got that specific test? It looks like it's their second IgG antibody test and their fourth overall[1]. It also looks like the architect moniker just seems to be their testing platform? I assume their previous IgG antibody test was built on it.

I don't know much about this space, would just like to get the test done and would prefer one with high specificity and low false positive rate.
