We report a nucleic acid test that integrates distinct mechanisms of DNA and RNA amplification optimized for high sensitivity and rapid kinetics, linked to Cas13 detection for specificity. We paired this workflow, termed Diagnostics with Coronavirus Enzymatic Reporting (DISCoVER), with extraction-free sample lysis using shelf-stable reagents that are widely available at low cost. DISCoVER has been validated on saliva samples to incentivize frequent testing for more widespread community surveillance and robustly detected attomolar levels of SARS-CoV-2 within 30 minutes, while avoiding false positives in virus-negative saliva. Furthermore, DISCoVER is compatible with multiplexed CRISPR probes to enable simultaneous detection of a human gene control or alternative pathogens.COVID-19 convalescent plasma, particularly plasma with high-titer SARS-CoV-2 (CoV2) antibodies, has been successfully used for treatment of COVID-19. The functionality of convalescent plasma varies greatly, but the association of antibody epitope specificities with plasma functionality remains uncharacterized. We assessed antibody functionality and reactivities to peptides across the CoV2 and the four endemic human coronavirus (HCoV) genomes in 126 COVID-19 convalescent plasma donations. We found strong correlation between plasma functionality and polyclonal antibody targeting of CoV2 spike protein peptides. Antibody reactivity to many HCoV spike peptides also displayed strong correlation with plasma functionality, including pan-coronavirus cross-reactive epitopes located in a conserved region of the fusion peptide. After accounting for antibody cross-reactivity, we identified an association between greater alphacoronavirus NL63 antibody responses and development of highly neutralizing antibodies to SARS-CoV-2. We also found
