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. It is most often ordered when a clinician is evaluating someone for a systemic autoimmune rheumatic disease, such as systemic lupus erythematosus, Sjögren syndrome, scleroderma, or mixed connective tissue disease. Because a positive result can occur in people without illness, the test is interpreted alongside symptoms, physical findings, and other laboratory results rather than as a stand-alone diagnosis.
About ANA Blood Test | Antinuclear Antibodies Testing in Tempe
The ANA test measures a class of antibodies that bind to structures inside the cell nucleus, including DNA, histones, and ribonucleoproteins.
The immune system normally produces antibodies against foreign invaders such as bacteria and viruses. In autoimmune conditions, antibodies may instead target the body's own tissues. The ANA test detects these self-directed antibodies in the blood.
Testing usually begins with an immunofluorescence assay, which reports a titer and a staining pattern. A titer indicates how much the sample can be diluted and still show reactivity; higher titers are more likely to be clinically significant, though low titers are common in healthy people. The pattern offers clues about which nuclear antigens may be involved.
When an initial ANA result is positive and the clinical picture suggests a specific disease, follow-up testing for individual antibodies, such as anti-double-stranded DNA, anti-Smith, anti-Ro, anti-La, anti-Scl-70, or anti-centromere, can help refine the assessment. The ANA test itself is a screening tool; it supports, but does not replace, a thorough clinical evaluation.
