Detection of Antinuclear Antibodies in SLE

The antinuclear antibodies (ANA) also known as antinuclear factors (ANF) are unwanted molecules which bind and destroy certain structures within the nucleus. In systemic lupus erythematosus (SLE), they are produced in excess; hence their detection in the blood of patients is important for diagnosis and monitoring of the disease. Several methods are available which can be used to detect ANA; nevertheless, indirect immunofluorescence antinuclear antibody test (IF-ANA) is considered a “reference method” for their detection. Though IF-ANA is relatively easier to perform, its interpretation requires considerable skill and experience. The chapter therefore is aimed to provide comprehensive details to readers, not only about its methodology but also the result interpretation and reporting aspects of IF-ANA.
