Furthermore, the 100 samples in our specificity panel were negative with the Alinity I SARS-CoV-2 IgG assay, except for one serum sample from a patient with coronavirus 229E infection, which was weakly reactive (signal-to-cutoff index ϭ 1.93; cutoff is 1.4 index), which leads to a specificity of 99%. While the clinical significance of SARS-Cov-2 antibody detection remains to be determined, our results confirm that careful evaluation of the tests on appropriate samples is required before implementing assays for routine use.	./cache/cord-324128-css42bsb.txt	./txt/cord-324128-css42bsb.txt
