What is the Test?
The Anti Nuclear Antibody (ANA) – Titre test detects the presence of antibodies that target components of the cell nucleus. ANA is commonly used to help diagnose autoimmune disorders such as systemic lupus erythematosus (SLE) and other connective tissue diseases.
Test Procedure:

The blood sample is sent to a laboratory for analysis. Laboratory technicians perform various tests to detect the presence of ANA antibodies.
When to Take the Test:
The ANA test is ordered when an individual shows symptoms of autoimmune disorders like joint pain, fatigue, skin rashes, and unexplained fevers.
Who Should Take This Test:
Individuals who are experiencing symptoms of autoimmune diseases, especially those associated with connective tissues, may be recommended to take the ANA – Titre test by their healthcare provider.

A: No, a positive ANA result indicates the presence of autoantibodies, but it doesn’t diagnose a specific disease. Further tests and clinical evaluation are required for a definitive diagnosis.
Q2. What conditions can a positive ANA result suggest?
A: A positive ANA result can be associated with various autoimmune disorders, including systemic lupus erythematosus (SLE), rheumatoid arthritis, Sjögren’s syndrome, and others.
