A complete blood cell count and measurement of liver enzymes and serum creatinine should be part of routine follow-up in JIA patients. For JIA patients receiving NSAIDs on a long-term daily basis, these tests, plus urinalysis, should be done twice yearly; in patients taking these agents 3-4 days per week, testing should be repeated annually.

In JIA patients taking methotrexate, these tests should be conducted approximately 1 month after initiation of routine use and approximately 1-2 months after any increase in dose. If prior results were normal and the patient is on a stable dose, the tests can be repeated approximately every 3-4 months.

In JIA patients taking TNF inhibitors, these tests should be repeated approximately every 3-6 months. Tuberculosis screening should be repeated approximately once yearly.
