Order ANA Blood Test | Antinuclear Antibodies TestingThe antinuclear antibody (ANA) blood test measures a specific class of autoantibodies that target components of a cell's own nucleus. Because these antibodies can appear in several autoimmune conditions, the test is often used as an early step when a systemic rheumatic disease is suspected.
About ANA Blood Test | Antinuclear Antibodies Testing in Chicago
The ANA test is a screening tool, not a diagnosis on its own.
Antinuclear antibodies are proteins produced by the immune system that mistakenly bind to structures inside the cell nucleus, such as DNA, histones, and ribonucleoproteins. A positive result indicates that such antibodies are present, but it does not by itself confirm a specific disease.
Clinicians commonly order an ANA test when a patient has persistent symptoms that suggest an autoimmune process, including joint pain or swelling, unexplained fatigue, skin rashes, or inflammation affecting multiple organ systems. The test is frequently part of the evaluation for conditions such as systemic lupus erythematosus, Sjögren's syndrome, scleroderma, and mixed connective tissue disease.
Results are usually reported as a titer, which reflects how much the sample can be diluted before antibodies are no longer detected, along with a staining pattern that offers clues about which nuclear targets are involved. A positive ANA can also occur in people without autoimmune disease, so the result is interpreted alongside symptoms, physical findings, and other laboratory tests.
