Anti-Nuclear Factor
Full Form of ANF
What is ANF?
Anti-Nuclear Factor (ANF) is an autoantibody that mistakenly targets the body's own cellular nuclei. The ANF test, also commonly referred to as the ANA (Anti-Nuclear Antibody) test, detects these antibodies in the blood. It is a primary screening tool for systemic lupus erythematosus (SLE) and other autoimmune connective tissue disorders. In India, the test is widely performed in hospital pathology laboratories and diagnostic centres, often prescribed by rheumatologists when patients present with symptoms like prolonged fatigue, joint pain, skin rashes, or unexplained fever. The test is also used to monitor disease activity in known cases. ANF testing is relevant for medical students, nursing candidates, and lab technicians appearing for Indian entrance or professional exams such as NEET PG, AIIMS, and state medical board examinations. Understanding its principle, methodology (indirect immunofluorescence or ELISA), and interpretation of titers and patterns is considered essential. A positive ANF result is not definitive on its own and requires correlation with clinical findings and other specific autoantibody tests such as anti-dsDNA. The test remains a cornerstone in the diagnosis of autoimmune diseases in India, where awareness and early detection are increasingly emphasized.
