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 are a hallmark of several autoimmune conditions, the test often serves as an early step in evaluating persistent joint pain, unexplained rashes, or other symptoms that suggest the immune system is targeting the body's own tissues.
About ANA Blood Test | Antinuclear Antibodies Testing in Arcadia
The ANA test measures the presence and concentration of antinuclear antibodies in the bloodstream.
Antinuclear antibodies are proteins produced by the immune system that bind to structures within the cell nucleus. While small amounts can occur in healthy people, higher levels or specific patterns of reactivity are associated with autoimmune diseases such as systemic lupus erythematosus, Sjögren's syndrome, scleroderma, and mixed connective tissue disease.
The test is typically ordered when a person has signs that could indicate an autoimmune process, including joint inflammation, muscle weakness, skin changes, or unexplained fever. It is also used to help distinguish among different autoimmune conditions, since the pattern and titer of ANA reactivity can offer clues about which disease is most likely.
Results are reported as a titer, such as 1:40 or 1:160, along with a staining pattern. A positive result does not by itself confirm an autoimmune disease, and a negative result does not rule one out. Clinicians interpret ANA findings alongside symptoms, physical examination, and other laboratory tests to reach a diagnosis and guide treatment.
