IgG positive on the Dia.Pro assay; we also retested a random subset of 164 samples that were 100

IgG negative. Notably, all 13 "positive" samples were anti-COVID-19 IgG negative, whereas 101 one sample out of 164 "negative" was IgG positive. 102

In order to test for a potential cross-reactivity in patients who resulted positive on either 103

Dia.Pro or Eagle ELISA, we also tested a few available "older samples" for IgGs (i.e. 104 obtained and frozen in a period when we assumed that the virus was not circulating).
