BTW, here’s a head scratcher for you...
Last year I had an antibody test for CoupFlu, both IgG and IgM..
Came back positive for antibodies indicating a current CoupFlu infection.
Per advice from doc, went back for a PCR a week later. Have no idea what the Ct in use was, I was never able to obtain that info, but the PCR came back negative.
Gave me great faith in the testing.
My understanding was...
Antibody test = previous infection
PCR test = current or recent infection
Your results make sense to me.
