diagnostic criteria for Sjögren's syndrome

Sjögren's syndrome is diagnosed based on a combination of symptoms, blood tests, and tissue exams. Key signs include dry eyes and mouth, along with other symptoms like fatigue or joint pain. Blood tests may show specific antibodies linked to the condition and signs of inflammation. Doctors may also perform eye tests to evaluate tear production and examine gland tissue from the salivary glands for inflammation or damage. A thorough evaluation of symptoms, lab results, and tissue studies helps confirm the diagnosis. The criteria aim to distinguish Sjögren's from other conditions with similar symptoms, ensuring accurate identification and management.
