Results are reported as AU/mL.The study findings showed that the acute infection of SARS-CoV-2 induces quick and robust ACE2-blocking and S-binding Ab responses. However, the Ab responses waned off around 11 months following ...94661-6 SARS-CoV-2 (COVID-19) Ab [Interpretation] in Serum or Plasma Active Term Description.

My test results caution that “it is yet undetermined what level of antibody to SARS-CoV-2 spike protection correlates to immunity against ...The SARS-CoV-2 RBD IgG test uses a recombinant form of the RBD region of the spike protein from SARS-CoV-2 attached to a solid support (ELISA plate) to capture IgG ... Final interpretation of ...Jun 30, 2021 · Therefore, we evaluated five different anti-SARS-CoV-2 antibody assays regarding the quantification of anti-spike (S) antibodies.
