A positive ANA test can be a sign of an autoimmune disease, where the immune system attacks healthy cells and tissues. 

ANAs are often associated with autoimmune diseases like systemic lupus erythematosus (SLE), Sjögren’s syndrome, and systemic sclerosis (SSc), among others. 

The ANA test is a blood test that looks for the presence and amount of antinuclear antibodies in your blood. 

A positive ANA test means that the test detected a higher-than-normal level of antinuclear antibodies in your blood. 

A positive ANA test may indicate a need for follow up blood tests, physical exam, and a review of history and symptoms. 

No, not always. Many healthy individuals can have detectable levels of ANAs, and the presence of ANAs alone doesn’t necessarily mean you have an autoimmune disease. 

The ANA test is used as a screening tool for autoimmune diseases, but it’s important to note that a positive ANA test doesn’t confirm a specific diagnosis. 

If you have a positive ANA test, your doctor may order further tests to help determine the cause of the elevated ANA levels and to rule out or confirm specific autoimmune diseases.
