MRP - ₹ 860
What is a ANTI NUCLEAR ANTIBODY / FACTOR (ANA/ANF) ELISA?
The Anti-Nuclear Antibody/Factor (ANA/ANF) ELISA test is a blood test used to detect autoantibodies that target structures within the cell nucleus. These antibodies are commonly associated with autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis, and scleroderma. The test is performed to help diagnose suspected autoimmune conditions, monitor disease activity, and guide treatment decisions. By identifying abnormal immune responses early, the ANA/ANF ELISA test supports timely medical intervention and improved patient management.

FAQs
No, ANA positivity alone does not confirm a specific disease. It indicates autoimmune activity, but further specific antibody tests are needed for diagnosis.
Yes, some healthy people may have low-level ANA positivity without disease. Clinical symptoms and additional tests are essential for interpretation.
Not always. High titers may suggest active disease, but severity depends on clinical findings and other laboratory results.
Yes, antibody levels may fluctuate. Doctors may repeat testing to monitor disease progression or treatment response.
No, it is not recommended for general screening. It is ordered when autoimmune disease is suspected based on symptoms.
Certain infections, medications, and even aging can sometimes cause false-positive ANA results.
It is not the primary tool for monitoring treatment, but changes in antibody levels may provide supportive information.
ELISA is automated and quantitative, while immunofluorescence is more traditional and considered the gold standard for ANA detection.
