Doctors worldwide usually suspect Juvenile Arthritis by examining the past health of the child. He looks for indicative symptoms such as joint pains, unusual swellings of the hands, knees, feet, rashes, fever or swelling in the lymph nodes. One of the most important ways of diagnosing this condition is to try and analyze the time frame of the persisting symptoms. Children who have been distressed with unusual joint related distresses for a period of 6 weeks or more are more likely to be suffering from this disease.

Sometimes an analysis of the health history of the child does not yield significant indicatives of Juvenile Arthritis. In such cases, laboratory tests are suggested by the doctors. Blood test is one of the easiest ways that help you learn about the presence of rheumatoid factor around the joints. These anti-bodies will only be detected in the blood of the patient suffering from this disease. Further, the blood test will reveal the presence of anti-nuclear anti-bodies. These proteins are released by the immune system only when the body is infected by an autoimmune disease.

X-rays are other sure-shot ways of detecting this disease. This test gives you a replica picture of your internal body which helps doctors to detect the presence of tumors, infections, bone fractures and other congenital defects.
