SARS-CoV-2 serology and autoantibodies were assessed using planar and bead-based arrays. Detected epitopes were validated in blood and cerebrospinal fluid from two independent cohorts of Neuro-COVID patients (n=25) and pre-pandemic healthy controls (n=29).</p><p dir="ltr">The datasets contain:</p><ul><li><b>SARS-CoV-2 serological profiles</b> measured in all samples (above) using 3-plex bead arrays. The data is reported as raw and normalized MFI (AU) and compound serostatus.</li><li><b>Proteome-wide autoantibody profiles</b> measured in 12 sample pools using planar arrays. The data is reported as median fluorescent intensity, in raw and normalized arbitrary units (MFI [AU]), and reactivity classification.</li><li><b>Targeted autoantibody profiles</b> measured in 478 healthcare workers and 48 patients across 5 time points using 363-plex bead arrays.
