If the anti-nuclear antibody (ANA) test is positive, it indicates that the patient has an autoimmune disorder, in which the body's own immune system attacks healthy cells. This can lead to a variety of symptoms, depending on the condition.
The most common autoimmune disorder associated with a positive ANA result is systemic lupus erythematosus (SLE). SLE can cause a wide range of symptoms, including joint pain, fatigue, rashes, and fever. It can also cause inflammation of the kidneys, heart, lungs, and/or brain, as well as anemia. Without proper treatment, SLE can damage the organs and cause serious complications.
Other conditions that may be associated with a positive ANA result include rheumatoid arthritis, myositis, scleroderma, and Sjögren's syndrome. Depending on the condition, treatment may involve medications, physical therapy, lifestyle changes, and/or surgery.
If the ANA test is positive, it is important to follow up with your doctor for further testing and treatment. Early diagnosis and treatment can help reduce the risk of serious complications.
