Use of test: The ANA has very limited use as a screening test. Nuclear scans are helpful in distinguishing inflammatory conditions (lupus, rheumatoid arthritis, myositis, etc.) versus non-inflammatory conditions. Pain with weight bearing and the lack of swelling suggest a mechanical cause. X-rays, MRI, and other tests may be more helpful than blood tests.
