Sensitivity is normally used in the context of measuring sensitivity to detect the disease, however, in the context of serology, you are only measuring sensitivity to antibodies, not SARS-CoV-2. Because antibody testing is not used for diagnosis, sensitivity is less important than specificity. The focus is on maximizing specificity for IgG so that we have no false positives. Sonora Quest ensures that test offered for SARS-CoV-2 IgG is extensively validated by the manufacturer to be highly specific. Sonora Quest is also performing our own validation using stringent acceptability criteria for precision, reproducibility, accuracy, method comparison, cross-reactivity, and clinical performance before starting patient testing.
