Sponsor's own description

The overall purpose of this observational cohort study is to characterize COVID-specific immune responses to SARS-CoV-2 exposure or COVID vaccination in a real-world setting. Participants will be asked to provide blood samples (either a normal venous blood draw, a few drops of blood obtained with a small finger-stick device, or both), as well as saliva or nasal swab sample at a series of visits. Subjects will receive results of the testing that is approved for routine clinical use (i.e., their AditxtScore), while residual samples from each visit will be stored for future testing. These efforts will support ongoing AditxtScore test development and enhance the effectiveness of its interpretation - aiding efforts to maximize benefits of clinical laboratory testing in the pandemic response.
