Delay between first symptoms of SARS-Cov-2 and quick serology test (in a), age (in b), Simplified Acute Physiological Score II (SAPS II, in c), and lymphocytes’ count on the day of quick serology test (in d). In a and b, red whiskers represent mean and standard deviation; in c and d, they represent median and interquartile range, due to non-Gaussian distribution. Comparisons between false-negative and true-positive test results were performed using t-test for delay and age, and Mann-Whitney test for SAPS II and lymphocytes’ count. Four-group comparisons were performed using analysis of variance (ANOVA) for delay and age, and Kruskal-Wallis test for SAPS II and lymphocytes’ count
