Neutralising antibody response dynamics in patients who have recovered from COVID-19 vary greatly, and prediction of immune longevity can only be accurately determined at the individual level. Our findings emphasise the importance of public health and social measures in the ongoing pandemic outbreak response, and might have implications for longevity of immunity after vaccination.
T-Detect has a high positive predictive agreement (97.1% per manufacturer) in convalescent sera from individuals with proven SARS-CoV-2 infection. A negative T-Detect COVID test does not exclude the possibility of prior infection from SARS-CoV-2, and to improve diagnostic accuracy, specimens should be obtained 15 days or more post symptom onset.
Atellica IM SARS-CoV-2 IgG (COV2G) assay is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. The concordance for the SARS-CoV-2 N IgG assays was 95.1% (Cohenโs ฮบ = 0.64; p = 2.5e-6).
