DFS70

The (test_name), also Anti-Dense Fine Speckled Protein 70 (Anti-DFS70) test detects antibodies targeting the DFS70 protein in the blood. These antibodies are often linked to autoimmune disorders, such as Systemic Lupus Erythematosus (SLE) or Sjögren's Syndrome. However, Anti-DFS70 antibodies can also appear in healthy individuals. This test is useful in identifying individuals who do not have an ANA-associated Autoimmune Rheumatic Disease (AARD), particularly when there are no significant clinical symptoms. When Anti-DFS70 antibodies are positive in isolation (without other AARD-associated antibodies), it can help prevent unnecessary tests for individuals who test positive for ANA but do not have an autoimmune condition.
