A member asked:
Hi, what are typical numbers from a labcorp sars-cov-2 semi-quantitative total antibody (spike, < .8 standard range) test months after pfizer vaccination? is 137.1 in a similar range of people who have been fully vaccinated? what are typical numbers?

Antibody reaction to a COVID-19 vaccine depends on individual and varied production, but if no vaccine was administered, this SARS-COVID-2 assay may have occurred from incidental infection with the COVID-19 virus, many of which occur without symptoms. If you were vaccinated, the response is also varied, but does indicate some immunity is present.

Is 137.1 (< .8 standard range) on a SARS-CoV-2 Semi-Quantitative Total Antibody (Spike) test from LabCorp months after vaccination similar to other vaccine antibody responses? What are typical numbers from that test after vaccination? Am I protected?
Hi, I got vaccinated early on with Pfizer and later got a SARS-CoV-2 Semi-Quantitative Total Antibody (Spike) test from LabCorp months later, result was 137.1 (< .8 standard range). I was wondering if this seems like a sufficient antibody response?
COVID-19 Antibody Test (SARS-CoV-2 AB IgG),Semi-Quantitative.Results:Positive.Reference range < 1.0 Index,Current > 150.00 Index.Boosted w/Moderna in Oct.Does positive mean that I had a prior covid infection or the result of the vaccination?
Immunocompromised- fully vaccinated and boosted I had a blood test SARS CoV-2 (COVID-19) antibody test. The results read POSITIVE >2500.0 u/ml. I was told that meant Ive build an immune response to Covid. Whats the chances of a false positive?
I had a SARS-CoV-2 Semi-Quant IgG Ab test done with LabCorp, the reference range is NEG less than 13.0 and my results are 48.6 AU/mL units. What does this mean? I know I tested positive for antibodies but is that a good number for protection?
