We here compared the sensitivity and specificity of seven commercial (SNIBE, Epitope, Euroimmun, Roche, Abbott, DiaSorin, Biosensor) and two in-house LIPS assays (LIPS N and LIPS S-RBD) IgG/total Ab tests in serum samples from 97 COVID-19 patients and 100 controls, and correlated the results with the patients' clinical data and the time-point the test was performed. Our study aimed to compare the performance characteristics of seven commercial and two in-house IgG/total Ab tests, which analyze the reactivity to several target proteins, and to correlate the results with the patients' clinical data (with different symptoms score and age), and time from disease onset.	./cache/cord-272445-0xauff51.txt	./txt/cord-272445-0xauff51.txt
