Characteristics of Three Different Chemiluminescence Assays for Testing for SARS-CoV-2 Antibodies
Figure 2
Positive predictive values (PPVs) of SARS-CoV-2 antibody titers at three different cut-offs (manufacturers’ cut-offs and half and double the manufacturers’ cut-offs) over the whole range of possible pretest probabilities. Three different chemiluminescence assays were assessed: (a) CMIA, (b) LIA, and (c) ECLIA.
