No idea what my levels are, but just tested positive for antibodies some 11 months after I was infected.

What does the below mean? That antibodies were present, but not enough to cross the threshold?

Very likely
Especially if it was a mild case.

"Most persons infected with SARS-CoV-2 display an antibody response between day 10 and day 21 after infection. Detection in mild cases can take longer time (four weeks or more) and in a small number of cases antibodies (i.e., IgM, IgG) are not detected at all (at least during the studiesí time scale)."

I had a mild case, 1.5 months later had 7/15 aka negative for antibodies, 3.5 months after infection got a positive antibody result (different test, no number given).

very likely you were exposed and it triggered a response

So....my daughter got the exact same results - which firstly seems odd. She tested negative twice after my wife tested positive, but I guess either they were false negatives or it's possible she had it before my wife and by the time she tested was already negative?

I got the same and I donít believe Iíve had COVID, multiple negative PCRs every time I thought I had symptoms.

Does the same apply for getting the vaccine? will I have a quantitative antibody count 21 days after the second dose?

I haven't been able to get titer levels yet.

It only recently got EUA approval: https://www.labcorp.com/coronavirus-disease-covid-19/news/roche-receives-fda-emergency-use-authorization-new-semi-quantitative-test-measure-level-sars-cov-2
Took this, 192.6 U/mL. Anything over 0.8 is considered positive.
The total range is 0.4-250 U/mL.

Curious how this compares to other people who had COVID or had the vaccine. But it's excellent news that 11 months later I'm still at the high end of the range.

How severe was your case? I thought they were saying that people with mild cases likely have lower antibody count.
