I’ve had the antibody test, which came out negative. But my doc seemed to suggest that it’s not really a good indicator as to whether you’ve actually been infected at some point (?)
(Though I suspect it may be more accurate than the PCR is. Gas-Dr?)
PCR is technically being used to diagnose active disease, but as been well elucidated elsewhere is not a great test because of the over amplification and while it may demonstrate presence of the virus in a sample, it may not quantify if sufficient to cause an infection. Its the old “true - true but unrelated” foil.
There is a narrow window of actual detectable antibodies usually around 90 days. After this — it gets to T-cell immunity with memory. So It is correct it is not a good indicator of infection unless caught within 90 days of symptoms.
