Clinical Conditions Associated With a High Antinuclear Antibody Titer in Individuals Without Autoimmune Disease

open access: yesArthritis Care &Research, EarlyView.
Objective Antinuclear antibodies (ANAs) are present at high titers in 2% of the general population, but their clinical significance in individuals without an autoimmune (AI) disease is not known. We tested the hypothesis that the presence of a high ANA titer in non‐AI conditions is associated with disease.
