The cross-reactivity testing of the immunosensor for detection of anti-SARS-CoV-2 IgG and IgM. (a) The cross-reactivity data of CR3022 IgG detection using total human IgG antibody as the interference protein. *p = 3.58 × 10−8. (b) The cross-reactivity data of CR3022 IgG detection using CR3022 IgM as the interference protein. **p = 1.01 × 10−8. (c) The cross-reactivity data of CR3022 IgM detection using CR3022 IgG as the interference protein. ***p = 6.27 × 10−6. In (a–b), ALP-labeled anti-human IgG was used as the detection antibody. In (c), ALP-labeled anti-human IgM was used as the detection antibody. For all the testing data, n = 5.
