Has anyone had a positive Anti-nuclear antibody titer result?
My Pdoc ordered this test a couple of years ago and I keep coming up positive.Should I let my Psychiatrist know about this. I wonder if it would be useful information.

A positive ANA usually means something is going on with your immune system, not your brain.

How is it used?
The ANA test is ordered to help screen for autoimmune disorders and is most often used as one of the tests to diagnose systemic lupus erythematosus (SLE). Depending on the patient’s symptoms and the suspected diagnosis, ANA may be ordered along with one or more other autoantibody tests. Other laboratory tests associated with presence of inflammation, such as erythrocyte sedimentation rate (ESR) and/or C-reactive protein (CRP) may also be ordered. ANA may be followed by additional tests that are considered subsets of the general ANA test and that are used in conjunction with the patient’s clinical history to help rule out a diagnosis of other autoimmune disorders.

When is it ordered?
The ANA test is ordered when a patient shows signs and symptoms that are associated with SLE or another autoimmune disorder. It may also be ordered when a patient has been diagnosed with an autoimmune disorder and the doctor suspects that the patient may have developed an additional autoimmune disorder. Patients with autoimmune disorders can have a wide variety of symptoms such as low-grade fever, joint pain, fatigue, and/or unexplained rashes that may change over time.
