The diagnosis of juvenile idiopathic arthritis (JIA) is based on the history and physical examination findings. No laboratory studies are diagnostic for JIA, and indeed, all laboratory study findings may be normal in children with this disorder. However, laboratory studies help to exclude other underlying disorders, classify the type of arthritis, and evaluate for extra-articular manifestations of JIA. Imaging of affected joints is usually indicated.

When physical findings do not document definite arthritis, further evaluation is warranted. The choice of studies varies on the basis of the specific circumstances.
