ANA TITRE (IMMUNOFLUORESCENCE)

The antinuclear antibody (ANA) titre test uses immunofluorescence to detect the presence and concentration of ANA in the blood. ANAs are autoantibodies that target the nuclei of cells and are commonly associated with autoimmune diseases such as systemic lupus erythematosus (SLE), Sjgren’s syndrome, and rheumatoid arthritis. The ANA titre test helps diagnose these conditions by measuring the level of ANA and identifying specific patterns of fluorescence that indicate different autoimmune disorders. A positive ANA test suggests the presence of an autoimmune condition and guides further diagnostic testing and treatment planning.
