Order ANA Blood Test | Antinuclear Antibodies TestingThe antinuclear antibody (ANA) blood test measures autoantibodies that target components of a cell's own nucleus. Because these antibodies can accompany several autoimmune conditions, the test is often used as a screening tool when a clinician is evaluating persistent joint pain, unexplained rashes, or other symptoms that suggest the immune system is attacking the body's own tissues.
About ANA Blood Test | Antinuclear Antibodies Testing in St. Peters
The ANA test is a blood draw that checks for autoantibodies directed against nuclear structures.
Antinuclear antibodies are proteins produced by the immune system that mistakenly bind to the nucleus of the body's own cells. A positive result does not by itself confirm a specific disease; it indicates that autoantibodies are present and may prompt further testing.
The test is commonly ordered when a patient has signs that could point to an autoimmune disorder, such as joint inflammation, muscle weakness, skin changes, or unexplained fatigue. It can also help monitor a known condition or distinguish between overlapping diagnoses.
Results are typically reported as a titer, which shows how much the sample must be diluted before antibodies are no longer detected, and sometimes as a pattern that hints at which nuclear components are targeted. A higher titer is more strongly associated with autoimmune disease, though low titers can occur in healthy people.
