While closely associated with diseases such as systemic lupus erythematosus ANA expression occurs commonly in healthy people. The basis for this expression is unknown although it may reflect features of the assays for antibody detection or intrinsic immunological disturbances in otherwise normal individuals. Like autoimmunity itself ANA expression is more common among women than men pointing to an important determinant of these responses. Future research will clarify the mechanisms of ANA expression and the utility of current assays as antecedent and screening biomarkers. Throughout medicine investigators are in hot pursuit of biomarkers. These biomarkers many of which involve multiplex assays or omic technologies come in a variety of flavors antecedent disease risk screening subclinical disease diagnostic staging and prognostic. Among their uses biomarkers can help elucidate genetic predisposition to disease and identify triggering events practically such markers can allow early diagnosis and treatment and the development of strategies for risk reduction. Although biomarker technology can be unbelievably complex the principles are straightforward and provide hope for improved patient outcomes. As the study by Li and colleagues in Arthritis Research and Therapy indicates 1 the use of antinuclear antibodies ANAs one of the most venerable tests in immunology as antecedent or screening biomarkers while potentially very informative faces major challenges.
