Here, we performed a pilot study to assess the levels of anti-SARS-CoV-2 antibodies in samples taken from 491 preepidemic individuals, 51 patients from Hopital Bichat (Paris), 209 pauci-symptomatic individuals in the French Oise region and 200 contemporary Oise blood donors. To avoid redundancy, we focused LIPS analysis to N, selecting it for its sensitivity regarding an intracellular viral protein not targeted by NAbs and S1 as it is described as a target of most NAbs. To establish the specificity of the assay, we first analyzed the same series of 40 sera we used for S-Flow and found all of the sera to be negative (Fig. S3 ). Sera from pre-epidemic individuals sampled between 2017 and 2019 (first row), hospitalized cases with confirmed COVID-19 (second row), paucisymptomatics individual from the Crépy-en-Vallois epidemic cluster (third row) and healthy blood donors (last row) were surveyed for anti-SARS-Cov-2 antibodies using four serological assays.	./cache/cord-285700-9q6vwoct.txt	./txt/cord-285700-9q6vwoct.txt
