I do not know about tests UK got. Yes I know if somebody got sick with light symptoms may not have antibodies. Last week Cuomo stated this test 3000 cases shown 13% exposed. As statistic researcher you may add % of were sick but no antibodies and you will have the valid number.
The point we should go over the hill.
Too many variables.
It might be not enough antibodies to fire the test ?? But enough for immunity, or just needs longer for the antibodies to build up ??
well it's =>13% how much greater, no way to tell.
Sweden without lockdowns is the best model to study, when the cases start coming down, it won't be, but that might be lockdown, it'll be over the hill. From that we can then gauge how big the hill is.
