Order ANA Blood Test | Antinuclear Antibodies TestingThe antinuclear antibody test, commonly called the 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 is often used as an initial step when a clinician is evaluating persistent joint pain, unexplained rashes, or other symptoms that suggest an immune system disorder.
About ANA Blood Test | Antinuclear Antibodies Testing in Fallbrook
The ANA blood test measures the presence and concentration of antinuclear antibodies in the bloodstream.
Antinuclear antibodies are proteins produced by the immune system that mistakenly target the body's own nuclear material. While a positive result can occur in healthy individuals, it is more frequently associated with autoimmune diseases such as lupus, Sjögren's syndrome, scleroderma, and rheumatoid arthritis.
The test is typically ordered when a patient has signs or symptoms that could indicate an autoimmune condition, including joint inflammation, muscle weakness, skin changes, or unexplained fatigue. It is also used to help monitor disease activity in people already diagnosed with certain autoimmune disorders.
Results are usually reported as a titer, which indicates how diluted the blood sample must be before antibodies are no longer detected. A higher titer suggests a greater amount of antinuclear antibodies, but the result must be interpreted alongside clinical findings and, in some cases, additional specific antibody tests.
