Comparison between UPT-POCT and ELISA. Thirty-nine serum samples were extracted from 27 COVID-19 patients during the acute phase of illness. Twenty-five-fold dilution was for sample No. 2, 400 folds dilution for seven samples (No. 4, 8, 12, 14, 15, 34, and 37), and 100 folds dilution for the remaining 31 samples. Each sample was tested three times using the two methods. a Detection results of UPT-POCT and ELISA. b Spearman correlation test was used to analyze the relationship between the two methods. c Comparison of the measure values of UPT-POCT (Black dots) and the T/C ratio calculated based on ELISA OD value according to the parameters (y = 1.258x + 0.209) of Fig. 1D (Light gray dots)
