Order ANA Blood Test | Antinuclear Antibodies TestingThe antinuclear antibody (ANA) test is a blood test that detects autoantibodies directed against components of the cell nucleus. Because these antibodies can accompany several autoimmune conditions, the test is often used as a screening tool when a clinician is evaluating unexplained joint pain, rashes, or other symptoms that suggest autoimmunity.
About ANA Blood Test | Antinuclear Antibodies Testing in Plainfield
The ANA test measures the presence and amount of antinuclear antibodies in the blood.
Antinuclear antibodies are proteins produced by the immune system that bind to structures within the cell nucleus. In healthy people, they are usually absent or present at very low levels. Their presence can indicate that the immune system is targeting the body's own tissues, which is a hallmark of autoimmune disease.
The test is most commonly ordered when a clinician suspects an autoimmune condition such as systemic lupus erythematosus, Sjögren's syndrome, scleroderma, or rheumatoid arthritis. It is often used alongside a medical history and physical examination rather than as a stand-alone diagnostic tool, because a positive result does not by itself confirm a specific disease.
Results are typically reported as a titer, which describes how much the sample can be diluted before antibodies are no longer detected, and sometimes as a staining pattern that offers clues about which antibodies are present. A negative result generally makes certain autoimmune conditions less likely, while a positive result may prompt additional, more specific testing.
