I saw my doctor last week for a non-Covid issue. I asked him if there is any merit to taking the antibody test. His point of view was the current anti-body test still has too many false positive and false negative readings to be of any value. He concluded his commentary by saying, “If I gave you the test, I don’t know what I would do with the results whether you tested positive or negative.”
Meanwhile every positive recorded on these tests is being presented in the media and by heath professionals (Faucci, state health directors) as indisputable fact, and decisions are being made to keep businesses shut down based on the data.
Antibody tests are not what is used purportedly due to inaccuracy but they are not what is used to detect current Covid infections.
There are many antibody tests. Some are more accurate than others.
Interesting link and, no, I don’t work for Roche. :-)
