Overview
Because there are no tests for JIA, the doctor will try to rule out other causes of arthritis and other diseases as the cause of the symptoms.
To diagnose JIA, the doctor will take a complete medical history that includes a description of symptoms and perform a physical examination. The doctor will also examine the joints for signs of arthritis.
The doctor may also order these tests:
- Imaging techniques such as X-rays or magnetic resonance imaging (MRI) to show the condition of the joints;
- Laboratory tests on blood, urine, and/or joint fluid to help determine the type of arthritis. These include tests to determine the degree of inflammation and the presence of the substances antinuclear antibody (ANA) and rheumatoid factor. These tests also can help rule out other diseases — such as an infection, bone disorder, or cancer — or an injury as the cause of the symptoms.
