Title: Evaluation of nine commercial SARS-CoV-2 immunoassays Document date: 2020_4_10
ID: 8cg5yj20_17
Snippet: To evaluate the sensitivities of the assays at different stages of COVID-19 disease, case sera were grouped according the duration of disease: early phase, 7 to 13 days after the onset of disease symptoms; middle phase, 14 to 20 days after the onset of disease symptoms; and late phase, ≥21 days after the onset of disease symptoms. The sensitivities of the assays ranged from 40 to 86% for the early phase samples, 67 to 100% for the middle phase .....

The sensitivities of the assays ranged from 40 to 86% for the early phase samples, 67 to 100% for the middle phase samples, and 78 to 89% for the late phase ( Figure 2 ).
