The Antinuclear Antibodies (ANA) test looks for the presence of antibodies which may indicate a person is suffering from an autoimmune disorder such as Lupus, Rheumatoid Arthritis, Sjogren's Syndrome or Scleroderma. Unlike normal antibodies, antinuclear antibodies attack the nucleus of the body's own cells causing damage to organs and tissues. Because the symptoms of autoimmune disorders can often be similar, ANA testing can help to narrow down the possible diagnoses. Results from this test should be interpreted by a person's doctor and may require follow up testing which is more specific to certain types of diseases.
It is important to note that positive ANA results are not definitive by themselves. Some people may test positive for antinuclear antibodies without having an autoimmune disorder. ANA production can also be triggered by conditions such as mononucleosis as well as some types of medications.
The ANA test is also included in our Arthritis Comprehensive Panel.
Turnaround time for the ANA test is typically 2-3 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
The Antinuclear Antibody test has no fasting requirements.
