What is Anti-Nuclear Antibody (ANA)?
Anti-Nuclear Antibody (ANA) is a type of antibody found in the blood that reacts to substances inside cells, such as nucleic acids and proteins. These antibodies are produced by the immune system to help protect the body from infection and other illnesses.
What Does a Positive ANA Result Mean?
A positive ANA result indicates that the person has an increased level of antibodies in their blood, which can be a sign of an autoimmune disorder. Autoimmune disorders are conditions in which the body's immune system mistakenly attacks its own cells and tissues. Examples of autoimmune disorders include lupus, rheumatoid arthritis, and Sjogren's syndrome.
What Tests Will Be Done After a Positive ANA Result?
Once a positive ANA result is obtained, the patient will likely undergo further testing to determine the specific nature of the autoimmune disorder. Tests may include a complete blood count (CBC), urinalysis, and specific antibody tests. Imaging tests such as X-rays, ultrasounds, or CT scans may also be ordered to evaluate the extent of tissue damage or organ involvement.
What Treatment Is Available for Autoimmune Disorders?
Treatment for autoimmune disorders will depend on the specific disorder. Treatment may include medications, such as corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs), to reduce inflammation and suppress the immune system. Physical therapy, lifestyle changes, and natural remedies may also be recommended to help reduce symptoms and improve overall health.
