Test Description
The Anti-Nuclear Antibody Test or ANA Test) test is a blood test that detects the presence of antinuclear antibodies (ANA) in the blood. ANAs are autoantibodies that attack the nucleus of cells in the body, which can lead to autoimmune disorders. The ANF test is also known as the Antinuclear Antibody (ANA) test.
Indications of the Test
The ANF test is used to help diagnose autoimmune disorders such as systemic lupus erythematosus (SLE), scleroderma, Sjögren’s syndrome, juvenile arthritis, or polymyositis and dermatomyositis[1][3]. It is also used to diagnose other health conditions that can cause antinuclear antibodies, such as viral infections, cancer, and liver diseases[1][2].
Patient Preparation/Instructions
No special preparation is required for the ANF test. However, patients should inform their healthcare provider of any medications they are taking, as some medications can affect the test results[1].
Typical Reference Values
A positive ANA test result indicates the presence of antinuclear antibodies in the blood. However, having a positive result does not necessarily mean that the patient has an autoimmune disorder. Many healthy people have positive ANF test results, particularly women over the age of 65[4]. The ANA test is not a definitive diagnostic tool for autoimmune disorders, and further testing may be required[1][3].
Turnaround Time
The turnaround time for the ANF test varies depending on the laboratory performing the test. Patients should consult with their healthcare provider or the laboratory for more information.
