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 systemic autoimmune disease, the test is frequently used as an initial screen when a clinician suspects an autoimmune process.
About ANA Blood Test | Antinuclear Antibodies Testing in Orange
The ANA test occupies a distinctive place in immunology: it is highly sensitive for certain conditions but not specific to any single one, which makes interpretation dependent on context.
Antinuclear antibodies are immunoglobulins that bind to nuclear structures such as DNA, histones, and ribonucleoproteins. They arise when the immune system loses tolerance to the body's own nuclear material, a process central to several connective tissue diseases.
A positive ANA result can occur in systemic lupus erythematosus, Sjögren syndrome, systemic sclerosis, mixed connective tissue disease, and autoimmune hepatitis, among others. It may also appear in some infections, certain medications, and in a proportion of healthy individuals, particularly at low titers.
Because of this overlap, an ANA result is rarely diagnostic on its own. Clinicians combine it with the patient's symptoms, physical examination, and more specific tests such as anti-dsDNA, anti-Smith, or anti-Ro/SSA antibodies to reach a conclusion.
