Abstract
Disclosed herein are immunoassays for detecting an antibody in a biological sample from a subject and/or diagnosing an autoimmune disease in a subject. The disclosed immunoassays use a single, direct step to assess the level of antibody in a biological sample from the subject by simultaneously binding the antibody to a capture antigen (e.g. an unlabeled antigen bound to a solid support) and a labeled antigen not bound to the solid support.
