In brief: See below
A lot of the diagnosis will be based on the history of joint swelling, redness, and pain.
And a physical exam that reveals the joint findings. Then, labs can be ordered to help confirm the diagnosis.

There are no labs that can confirm the diagnosis of JRA. It is purely a clinical diagnosis that can be confirmed, if necessary (often not necessary), with an MRI with and without contrast that can show low grade but real joint inflammation (synovitis) if there are no obviously swollen joints on exam but there is morning stiffness that improves with movement. Labs can be completely normal and still have JRA. Rheumatoid factor and ANA tests are USELESS for diagnosing JRA in kids.

In brief: JA- teen diagnosis
The diagnosis is made when there has been arthritis in the joints for greater than 6 weeks.
Children may have normal blood work such as a normal ANA test and a normal rheumatoid factor test. The diagnosis is made based on the physical exam and not based on blood work.
