The Antinuclear Antibodies (ANA) test measures antibodies in your blood that mistakenly target your own cells, a process known as an autoimmune reaction. These antibodies are commonly associated with autoimmune and connective tissue disorders, making this test a key first step in evaluating unexplained inflammation, fatigue, joint pain, or systemic symptoms. ANA testing is widely used to help identify immune system dysfunction and support the diagnosis of autoimmune conditions. Because ANA patterns can provide important clinical clues, results are interpreted alongside symptoms and additional lab findings to guide accurate diagnosis and next steps. What Is Included In This Test? This test detects the presence and pattern of antinuclear antibodies in your blood using validated laboratory methods. Your results can help: Screen for autoimmune and connective tissue diseases Support diagnosis of conditions such as lupus, Sjögren’s syndrome, and scleroderma Evaluate immune system activity related to chronic inflammation Assist in diagnosing drug-induced autoimmune conditions Guide further autoimmune-specific testing when needed Who Should Consider This Test?
