Description:

Antinuclear Antibody (ANA) Blood Test

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.

Can COVID Cause Positive ANA Results?

Studies have shown that the COVID-19 virus can trigger the production of ANA as well as some other types of autoantibodies.  These antibodies can persist well after the immediate COVID infection has been resolved.  Many people have reported long-term symptoms including fatigue, joint pain, muscle aches, and difficulty with memory, attention span, or coordination.  Taking an ANA blood test after COVID can help identify the cause of common "Long-COVID" symptoms and help a person work with their doctor to develop an effective treatment plan.

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 3-5 business days.
