Abstract: Provided are methods and compositions for determining whether an individual has Sjögren's disease (SD). The method entails determining in a biological sample from the individual the presence of antibodies directed to salivary gland protein 1 (SP-1), parotid secretory protein (PSP), carbonic anhydrase 6 (CA6), or determining a combination of the antibodies. Determining that the individual has SD is based on the presence of the antibodies. The method provides for detection of early SD. Kits for antibody detection containing the antigens to which the antibodies of SD patients are directed are also provided.
