Order ANA Blood Test | Antinuclear Antibodies TestingThe antinuclear antibody (ANA) blood test measures a specific class of autoantibodies that target structures within a cell's nucleus. Because these antibodies can appear in several autoimmune conditions, the test is often used as an early step when a clinician is evaluating persistent joint pain, unexplained inflammation, or symptoms that suggest the immune system is misdirecting its activity.
About ANA Blood Test | Antinuclear Antibodies Testing in Aiken
The ANA test is a screening tool, not a diagnosis on its own.
Antinuclear antibodies are proteins produced by the immune system that bind to components of the cell nucleus, such as DNA, histones, and ribonuclear proteins. In healthy people, these antibodies are usually absent or present at very low levels. When they are detected in higher concentrations, they can point toward an autoimmune process, though the result must always be interpreted alongside symptoms, physical findings, and other laboratory work.
The test is most commonly ordered when a clinician suspects an autoimmune disease such as systemic lupus erythematosus, Sjögren's syndrome, scleroderma, or mixed connective tissue disease. It is also used to help distinguish autoimmune arthritis from other forms of joint disease. A positive result does not confirm a specific condition, and a negative result does not entirely rule one out, because some autoimmune diseases can occur without a detectable ANA.
Results are typically reported with a titer and a pattern. The titer indicates how dilute the sample must be before antibodies are no longer detected, and higher titers are generally more significant. The pattern describes how the antibodies distribute within the cell, which can offer clues about which nuclear targets are involved. Follow-up testing for specific antibodies, such as anti-dsDNA or anti-Smith, may be ordered when the ANA is positive and a particular diagnosis is being considered.
